Consensual Nonmonogamy: Psychological Well-Being and Relationship Quality Correlates

Romantic relationship configurations and their correlates among LGBTQ+ persons: A latent class analysis

Research comparing monogamous and non-monogamous relationships on well-being indicators across diverse populations have yielded inconsistent findings. The present study investigates sociodemographic characteristics, as well as personal and relational outcomes, across different relationship configurations. Data were drawn from an online community-based sample of 1,528 LGBTQ+ persons aged 18 years and older in Quebec, Canada. A latent class analysis was performed based on legal relationship status, relationship agreement, cohabitation status, and the seeking of extradyadic sexual and romantic partners on the internet. Class differences on sociodemographic characteristics and well-being and relationship quality indicators were examined. A five-class solution best fit the data, highlighting five distinct relationship configurations: Formalized monogamy (59%), Free monogamy (20%), Formalized open relationship (11%), Monogamous considering alternatives (7%) and Free consensual non-monogamies (3%). Cisgender women were more likely to engage in monogamous relationships than cisgender men, who were overrepresented in open relationships. Lower levels of perceived partner support were observed in both free monogamous and consensually non-monogamous relationships, the latter of which also showed lower levels of well-being. Consensual non-monogamy researchers exploring relationship outcomes should examine relationship facets that go beyond relationship structure or agreement. Variations in monogamies and non-monogamies, both consensual and non-consensual, may be present within each broad relationship configuration, as reflected in different personal and relational needs, which can then translate to better or poorer outcomes.

Navigating Stigma in Romantic Relationships Where One or Both Partners Sell Sexual Services

Romantic relationships are an important part of our social identities and well-being. In this paper, we report on qualitative findings with thirty Canadian couples, interviewed together, where it was known that one or both partners sell sexual services for a living. We asked a series of open-ended questions related to the background of the couple's relationship, their day-to-day interactions and work-related stressors. Participants talked about the ongoing negotiations they engage in as a couple, the benefits of being open to each other about working in the sex industry, and how they manage its emotional toll on their partnership. We conclude that there are various ways that sex workers are able to maintain intimacy in their romantic relationships after sex work has been disclosed. Widespread social stigma attached to sex work, complicated by criminalization in countries such as Canada, nevertheless threatens relationship quality in the long run.

Psychometric Properties of the Attitudes Toward Polyamory Scale (ATP) in the Spanish Context

Given the potential discrimination faced by individuals in polyamorous relationships, understanding attitudes toward polyamory in society is crucial. To this end, instruments to measure attitudes toward polyamory with adequate psychometric properties are necessary. The aim of this study was to adapt the Attitudes Toward Polyamory Scale (ATP) to the Spanish context and analyze its psychometric properties in a sample of young adults. The sample comprised 1,162 individuals aged 18 to 35 years. Participants responded to sociodemographic questions and completed the Revised Sexual Opinion Survey (SOS) and the ATP. The findings indicate: (1) adequate reliability coefficients, (2) good fit statistics for the one-factor confirmatory model that verify results of exploratory factor analysis, (3) that homosexual and bisexual people have more favorable attitudes toward polyamory than heterosexual, (4) positive correlations between ATP scores, SOS scores, and political orientation (individuals with higher levels of erotophilia and a more left-leaning political orientation tend to hold more favorable attitudes toward polyamory), and (5) association between ATP scores and religion, with non-religious individuals showing more favorable attitudes toward polyamory than Catholics. In conclusion, the ATP demonstrates adequate psychometric properties in Spanish young adults.

Perceived Impacts of Partners' Other Relationships on Oneself in Consensual Nonmonogamy

Existing research suggests a number of both costs and benefits to oneself that can occur as a result of partners' other relationships in consensual nonmonogamy (CNM), but such costs and benefits have not previously been systematically cataloged. Using reflexive thematic analysis, we present themes derived from semi-structured interviews with 51 individuals (63% white, 55% nonbinary/genderqueer/non-cisgendered, and 77% LGBQ) who have practiced CNM, describing the costs and benefits to themselves that they perceive as a result of their partners' other relationships. Themes describing costs include experiencing difficult feelings (e.g., jealousy), having less with a partner (e.g., less of a partner's time) than one would like, difficulties or conflict within one's own relationship, and difficulties or conflict as a result of interactions between metamours (individuals who share a partner). Themes describing benefits include experiencing positive feelings (e.g., compersion), benefiting from a partner getting needs met in other relationships, strengthening of or pleasurable interactions within one's own relationship, enjoyable or beneficial relationships or interactions between metamours, and personal growth as a result of sharing partners with others. We note that these costs and benefits roughly mirror each other, suggesting that they may reflect the positive and negative sides of some fundamental aspects of CNM. Each of our themes also contains a rich range of elements that suggest avenues for future research. Our results suggest that CNM relationships are complex and multi-faceted, and that further research could fruitfully examine the circumstances that influence whether individuals experience their partners' other relationships positively or negatively.

A Narrative Review of the Dichotomy Between the Social Views of Non-Monogamy and the Experiences of Consensual Non-Monogamous People

Monogamy is deeply rooted in most Western societies, shaping how people construe and behave in romantic relationships. These normative views facilitate the emergence of negative perceptions and evaluations when people choose not to adhere to mononormativity. Even though people in consensual non-monogamous (CNM) relationships are targets of stigmatization, research shows a dichotomy between these negative views and the relational experiences of CNM people. Indeed, people in CNM and monogamous relationships have comparable relationship functioning and quality and struggle with similar relationship problems. One of the differences is that CNM relationships afford people to explore their sexuality and fulfill their needs with multiple partners, without agreed-upon extradyadic behavior being perceived as infidelity or having deleterious consequences to relationship maintenance. These positive experiences notwithstanding, CNM people are continuously pressured by mononormativity and stigmatization, increasing the risk of internalized CNM negativity and worse personal and relational outcomes. One possible way to counteract CNM stigmatization and improve the lives of CNM people is by changing discourses surrounding non-monogamy and improving acceptance, not only in professional settings but also in the general population. Another strategy is to understand how the relationship beliefs and scripts of younger generations can help promote more inclusive and diverse societies.

Emerging Adults' Perspectives on Consensually Nonmonogamous Parenting

Consensual nonmonogamy (CNM) is increasingly recognized as a relevant aspect of family and relational diversity in the USA, but CNM-parenting is still perceived as a taboo topic. Pioneering research has only started to emerge and reveals persisting notions of regulation, discrimination, and stigmatization of CNM-parents. CNM-stigmatization is less prevalent among emerging adults, but it is unclear whether young adults' increasing acceptance of CNM relationships extends to their views on parenting. To explore emerging adults' perspectives on CNM-parenting, we conducted a mixed-method study with a diverse sample of 107 US-American college students. Each participant read four relationship-vignettes (monogamy, CNM-polyamory, CNM-open relationship, CNM-swinging) in randomized order, provided ratings for the perceived parenting capabilities of the described partners and described reasons for those ratings in short essays. On average, participants perceived the monogamous partners as more capable of raising children than the CNM partners. LGBTQ + participants perceived CNM-parents, especially polyamorous and swinging partners, as more capable for parenthood than did heterosexual participants. There were no significant differences in response patterns between males and females. In their essays, participants discussed their views on how the different relationship structures might affect parenting and what they perceived as indicators and conditions for successful parenting. The results of this study were interpreted relative to life-course perspectives of identity development, and relative to politico-economic perspectives on parental investment and sexual strategy theories. Implications are derived for sexuality education, research, and practice.

What do we know about consensual non-monogamy?

Recent years have seen considerable interest in consensual non-monogamy from both public and academic perspectives. At least 5% of the North American population is currently in a consensually non-monogamous relationship of some form and there is little difference in measures of relationship quality compared to monogamous relationships. Despite increasing levels of understanding and engagement many practitioners of consensual non-monogamy still experience stigma (and minority stress) which is exacerbated by context (e.g. parenting, healthcare settings), type of consensual non-monogamy (e.g. polyamory vs swinging) and intersects with other identities (e.g. race, sexuality). This review outlines what is currently understood about consensual non-monogamy and argues that relationship diversity has a place alongside gender and sexuality when studying sexual behaviours, romantic relationships, and well-being.

Stigmatization of Consensual Non-Monogamous Partners: Perceived Endorsement of Conservation or Openness to Change Values Vary According to Personal Attitudes

Studies have shown that romantic partners in consensual non-monogamous (CNM) relationships are targets of stigmatization. However, little is known about the underlying mechanisms and the conditions under which such stigmatization occurs. In two experimental studies (combined N = 772), we asked participants to read the description of two partners in a relationship (monogamous vs. open relationship vs. polyamorous) and make a series of judgments about those partners. Overall results showed that CNM (vs. monogamous) partners were perceived as less trustworthy and as having more sexual health concerns (Studies 1 and 2), and as being less committed and less sexually satisfied (Study 2). Results from a conditional mediation analysis (Study 2) further showed that participants with negative attitudes toward consensual non-monogamy perceived CNM (vs. monogamous) partners as having less conservation and more openness to change values, which was then associated with more stigmatization. In contrast, participants with positive attitudes toward consensual non-monogamy perceived CNM (vs. monogamous) partners as having more openness to change values, which was then associated with less stigmatization. Taken together, these results extended the literature focused on prejudice, discrimination, and stigmatization of minority groups and highlighted key elements that can be used to buffer stigmatization.

Motivation of non-monogamous adults to engage in sex with their different partners

This study compared motivations of individuals in non-monogamous relationships to engage in sex with their different partners (n = 596, out of which 103 non-consensual non-monogamous, 135 polyamorous, 204 swinging, 154 in open relationships; women-38.8%, men-59.7%, other gender-1.5%; age range: from 18 to 65+ years; 86% of respondents between 25 and 54 years old; majority of the respondents are in a long-term relationship). The research aim was to identify whether there are differences in reasons to engage in sex with respondents' primary versus secondary partners. Presented with 17 reasons to engage in sexual activity, the respondents rated the frequency with which they engage in sex for each reason with their different partners. Questions for 14 reasons to engage in sex were created based on the YSEX? questionnaire and three questions were created specifically for non-monogamous population. The three new questions addressed the desire for a specific type of sex (such as kink, fetish, etc.), desire to have sex with a partner of another gender than one's primary partner, and desire to experience the thrill of the forbidden. The results indicated that there are significant differences in motivation to engage in sex with one's primary versus secondary partner for most of the reasons. Additionally, this study investigated whether there are differences in motivation to engage in sex with different partners depending on the relationship arrangement. The data analysis shows that there are differences in reasons to engage in sex with one's different partners between non-consensually and consensually non-monogamous groups. This research compliments existing body of research with new reasons to engage in sex, it demonstrates that non-monogamous people engage in sex with their different partners for different reasons and reveals that these may vary depending on the type of the relationship arrangement.

Challenges and Benefits of Disclosure of Sex Work to Intimate Partners

Sex workers' noncommercial intimate partnerships are marginalized on two counts - they are non-monogamous and at least one partner is in sex work, an occupation with much stigma. We asked a heterogeneous sample of Canadian sex workers (N = 218) about their decisions to reveal/not reveal their sex work to intimate partners, and the resulting challenges and benefits. A minority (58/183) of participants who had been or were currently involved in an intimate relationship kept their work secret from at least one partner or disclosed limited information, shielding them from stigma but resulting in a burden of secrecy. The majority of participants (151/183) who had been/were currently involved in an intimate relationship chose to disclose their sex work to at least one partner, which for most, had one or more negative consequences. A small group of participants related that disclosure resulted in acceptance, support, and understanding from their intimate partner. Some participants avoided the disclosure dilemma by forming intimate relationships from social connections where sex work status was already known. These relationships were generally supportive. We conclude that intimate relationships provide positive experiences for many people who sell sexual services and that these relationships could be stronger if societal stigma was reduced.

Under-Representation of Transgender Identities in Research: The Limitations of Traditional Quantitative Survey Data

Purpose

Research indicates that the portrayal and representation of transgender individuals within society, or lack thereof, impact the way in which they are able to reconcile their gender identity. Quantitative research methodology often requires that participants select one identity label from a limited list for each identity characteristic (e.g., race, sexual orientation, and relationship status). The process of choosing from limited items that do not represent one's identities limits our understanding of the nuances of identity and may create minority stress for the participant.

Methods

This study included 325 diverse transgender adults who participated in a national anonymous online survey as part of a broader study focused on minority stress and mental health. Participants answered questions about gender, sexual orientation, relationship status, race, and religion, and were given the option to select multiple response options and to write in additional identities that were not listed.

Results

Descriptive results indicated that 95 unique gender identities written in were not captured by the 14 gender labels provided, over 43% of participants selected multiple sexual orientations, and participants wrote in additional options for every identity variable.

Conclusion

The nuance of transgender identities may not be adequately captured by standard demographic research methodologies and research would benefit from ongoing revision of demographic response options informed by the literature. Through the process of acknowledging and validating less visible identities, transgender individuals will be better represented and understood by researchers.

Are the Developmental Features of Emerging Adulthood Associated with Willingness to Engage in Consensually Nonmonogamous Relationships?

The purpose of this study was to examine whether the developmental features of emerging adulthood were associated with willingness to engage in consensually nonmonogamous (CNM) relationships. All participants (N = 792) were English speaking emerging adults (ages 18-25) residing in the USA. About half were attending college, whereas the other half had no college experience. After controlling for a number of variables (i.e., college status, sex/gender, sexual orientation, sexual identity exploration, sexual identity commitment, and casual sex attitudes), greater perceptions of emerging adulthood as a time of identity exploration and feeling in between were negatively associated with willingness to engage in CNM relationships. Also, greater perceptions of emerging adulthood as a time of experimentation/possibilities was positively associated with willingness to engage in CNM. Although our final model explained 33.5% of the variance in willingness to engage in CNM relationships, perceptions of the developmental features of emerging adulthood accounted for just 4.2% of the variance explained. Future research on CNM relationships and relationship education for emerging adults are discussed.

BDSM: Does it Hurt or Help Sexual Satisfaction, Relationship Satisfaction, and Relationship Closeness?

This national web-population study from Norway (N = 4,148) assessed 1) the prevalence of BDSM and role-play interests and behaviors, 2) the socio-demographic characteristics of the BDSM-oriented participants, and 3) the associations between a) BDSM and b) role-play interests and behaviors, and sexual satisfaction, relationship satisfaction, and relationship closeness. Over one in three study participants endorsed at least one BDSM interest or behavior variable. There were no gender nor educational level differences between the BDSM-oriented participants and their traditional "vanilla" (non-BDSM-oriented) counterparts, though BDSM and interests were more common among younger and self-identified LGBQ+ participants. Sexual satisfaction was positively associated with role-play and BDSM behaviors while interest in role-play (but not having previously engaged in it) was negatively associated with this outcome. Lower relationship closeness was associated with an interest in role-play (but not having tried it). No BDSM-related variables were significantly associated with relationship closeness. The findings suggest that BDSM interests and behaviors are relatively common and are linked with sexual and relationship satisfaction.

Differences in Motivation to Engage in Sexual Activity Between People in Monogamous and Non-monogamous Committed Relationships

This study compared motivations to engage in sex between monogamous and non-monogamous respondents (n = 1,238, out of which 641 monogamous and 596 non-monogamous respondents; women-47.4%, men-50.9%, other gender-1.7%; age: M = 27.78 years, SD = 7.53, range = 18-62). The research aim was to identify whether there are differences in self-reported reasons to engage in sexual activity between these two groups. Presented with 17 reasons to engage in sexual activity, the respondents rated the frequency with which they engage in sex for each reason. While both monogamous and non-monogamous respondents reported to engage in sex with the same frequency for the reasons of sexual release and physical desirability of a partner, the research uncovered that non-monogamous respondents engage in sex significantly more often to seek new experiences, to boost self-esteem, to guard their mate, to have a specific kind of sex (such as anal, kink, or fetish) or to experience the thrill of the forbidden. Non-monogamous respondents reported higher frequency to engage in sex for most reasons overall. The study also revealed that there are differences in reasons to engage in sex among men and women, some of the differences are related to the relationship status (monogamous or non-monogamous), while others are universal for men or women irrespective of their monogamy status.

Hypersexuality in Mixed-Sex Couples: A Dyadic Longitudinal Study

Emotion dysregulation and intimacy problems are theoretically underpinned correlates of hypersexuality (i.e., uncontrollable sexual urges, fantasies, and behaviors resulting in distress and impairment in different areas of functioning), but the directionality of these associations has not been established, as work in this area has relied on cross-sectional designs. Moreover, although hypersexuality may have significant adverse effects on romantic relationships and approximately half of treatment-seeking individuals are in a relationship, prior studies almost exclusively involved samples of men, regardless of their relationship status. The aim of the present study was to examine the directionality of associations between both partners' emotion dysregulation, physical (i.e., partnered sexual frequency) and relationship intimacy, and hypersexuality using a longitudinal, dyadic framework. Self-reported data of 267 mixed-sex couples (M_{age_men} = 29.9 years, SD = 8.2; M_{age_women} = 27.7 years, SD = 6.7) at baseline (T1) and six-month follow-up (T2) were analyzed using a crossed-lagged model within an actor-partner interdependence framework. Prior greater emotion dysregulation (T1) in both men and women was associated with their own later greater hypersexuality (T2). Women's prior greater hypersexuality (T1) was associated with their later lower relationship intimacy (T2). Lower levels of intimacy were not significantly associated with later hypersexuality. No partner effects were found in relation to hypersexuality. Findings suggest that men and women may use sexual behaviors to cope with negative emotions, which could, in turn, lead to hypersexuality. Intimacy problems did not precede hypersexuality, although women's hypersexuality may reduce their own relationship intimacy over time.

Does "Open" Rhyme with "Special"? Comparing Personality, Sexual Satisfaction, Dominance and Jealousy of Monogamous and Non-monogamous Practitioners

Romantic relationships are changing in Western culture. The recent rise of alternative relationship models called consensual non-monogamies (CNMs) has drawn attention toward them. Western cultures largely stereotype and stigmatize CNMs, portraying their practitioners (among other aspects) as psychologically distinct from monogamous practitioners. Likewise, recent scientific literature suggests probable differences for CNMs practitioners, mainly them being more extraverted, agreeable, and open, but also less jealous and dominant toward their romantic partners. However, although CNMs differentiate themselves from cheating monogamous practitioners, potential differences are unclear. The present study compared 372 participants (with 193 CNMs practitioners) from Spanish culture regarding their personality, sexual satisfaction, dominance, and jealousy. On most dimensions, monogamous and CNMs practitioners did not differ significantly from each other. CNMs practitioners showed significantly higher openness and lower conscientiousness, although these differences were small and debatable; thus, these findings should be taken with caution. These differences could not be explained by differences in age, gender, education, marital status, sexual orientation, or other demographic variables. The addition of cheating monogamous mitigated these differences. Overall, this study suggests that monogamous and non-monogamous practitioners are not psychologically different. Methodological limitations and future recommendations are discussed, with particular emphasis on replication studies.

Comparing the Self-Reported Health, Happiness, and Marital Happiness of a Multinational Sample of Consensually Non-Monogamous Adults with Those of the U.S. General Population: Additional Comparisons by Gender, Number of Sexual Partners, Frequency of Sex, and Marital Status

The primary objective of this cross-sectional study was to examine the associations of self-reported health, happiness, marital happiness, frequency of sexual activity, and number of partners from a multinational survey of individuals who are consensually non-monogamous (CNM) or open to being CNM, completed in 2012 with 4062 respondents. We compared data from this survey with the 2010-2014 US General Social Surveys (GSS). This study explored these variables and their predictors by gender (including 612 non-binary-gendered CNM individuals), marital status, number of partners, sexual frequency, age, education, and income and were broken down by behavioral sexual orientation, marital status, and other relevant categories. Respondents in our CNM sample generally reported being as healthy (sometimes healthier; e.g., all respondents M-W Z = 7.66, p < .001, η² = 0.007), happy (frequently happier; e.g., multiple-partnered Z = 15.43, p < .001, η² = 0.069), happy in their marriages (in some cases happier; e.g., multiple-partnered females Z = 2.61, p = .009, η² = 0.067), and reported having more frequent sexual activity (e.g., all Z = 29.54, p < .001, η² = 0.094) with more partners (e.g., all Z = 60.75, p < .001, η² = 0.393) compared to corresponding individuals within the GSS. This study contributes to knowledge about commonalities and differences between the general population and those who are CNM regarding health, happiness, and happiness in marriage, including differences in optimal number of sexual partners and sexual frequency.

Sameness and Difference in Psychological Research on Consensually Non-Monogamous Relationships: The Need for Invariance and Equivalence Testing

Comparative research involving consensually non-monogamous (CNM) relationships and outcomes related to well-being continues to grow as an area of interest within sexual science. However, claims of sameness and/or difference between groups rely on two critical, yet widely under-appreciated assumptions: that the concepts being compared between groups are the same (i.e., measurement invariance), and that logically and statistically coherent procedures are used for evaluating sameness (i.e., equivalence testing). We evaluated the state of measurement invariance and equivalence across three studies, involving different types of CNM comparisons (i.e., relationship types, partner types) and designs (analysis of primary individual data, primary dyadic data, and secondary data). Our invariance tests of CNM compared to monogamous individuals (Study 1) and "primary" compared to "secondary" partners in dyadic appraisal of CNM individuals (Study 2) revealed that many measures of well-being failed to replicate their measurement models and were not generalizable across relationship types or partner types. Our reanalyses of existing comparative CNM effects using individual and meta-analyzed equivalence tests (Study 3), meanwhile, indicated that this literature requires more consistent reporting practices and larger samples, as most studies produced uninformative tests of equivalence. Our results illustrate the importance of auxiliary hypothesis evaluation and statistical procedure selection for generating informative comparative tests. Our findings also highlight potential divergences in social construction of well-being. We offer suggestions for researchers, reviewers, and editors in terms of needed methodological reforms for future comparative CNM research.

With or Without You: Associations Between Frequency of Internet Pornography Use and Sexual Relationship Outcomes for (Non)Consensual (Non)Monogamous Individuals

More frequent internet pornography use is often associated with decreased sexual satisfaction. However, individuals who use internet pornography more often can experience better relationship outcomes, depending on how they use it in the context of their relationship. Indeed, internet pornography use with the partner seems to be positively associated with sexual satisfaction. We explored whether the type of agreement partners have about monogamy is related to this association. We conducted a cross-sectional study (N = 866; 66.3% women, Mage = 27.40, SD = 8.58) with individuals in monogamous (n = 552), non-consensual non-monogamous (NCNM; n = 210) and consensually non-monogamous (CNM; n = 104) relationships. Results showed that CNM individuals used internet pornography substantially more than the other two groups, but they were as sexually satisfied with themselves and with their primary partner as monogamous individuals. NCNM individuals were the least sexually satisfied and reported more sexual arousal difficulties than the other groups. Results further showed that CNM individuals included their primary partner in their internet pornography use more frequently than the other groups, and this inclusion was positively associated with sexual satisfaction with the primary partner. The frequency of internet pornography use with the partner was negatively associated with sexual arousal difficulties for monogamous individuals and positively associated with personal and relational sexual satisfaction in both monogamous and NCNM individuals. These results complement past findings by shedding light on the role of internet pornography use for different relationship agreements, and its association with personal and relational experiences.

Exploring Minority Stress and Resilience in a Polyamorous Sample

Polyamory is a type of consensual non-monogamy (CNM) in which participants engage in multiple simultaneous romantic and often sexual relationships with the knowledge and consent of all involved. CNM practitioners in general, and polyamorous people in specific, appear to be highly stigmatized due to their relational practices, and to experience acts of CNM-related discrimination, harassment, and violence. Conceptualizing this dynamic via minority stress theory predicts that this stigma and discrimination will lead to negative mental health effects for polyamorous individuals. However, recent research has begun to identify possible sources of resilience within polyamorous populations that may ameliorate these negative effects. This study investigated these hypotheses in a sample of 1176 polyamorous American adults utilizing structural equation modeling. Four constructs were assessed as potential resilience factors: mindfulness, cognitive flexibility, a positive CNM identity, and connection to a supportive CNM community. Results indicate that CNM-related minority stress was positively related to increased psychological distress, such as higher self-reported depression and anxiety symptoms. Mindfulness was found to have both direct and moderating effects on the relationship between minority stress and psychological distress, such that higher mindfulness attenuated the negative impact of minority stress. Cognitive flexibility also displayed direct and moderating effects, but in the opposite than predicted direction. Clinical and research implications of these findings are discussed, with an emphasis on expanding understanding of how anti-CNM stigma affects practitioners and improving clinical cultural competence with this unique and under-served population.

Are there "Better" and "Worse" Ways to be Consensually Non-Monogamous (CNM)?: CNM Types and CNM-Specific Predictors of Dyadic Adjustment

Research on consensual non-monogamy (CNM) has largely been restricted to comparisons between monogamous and CNM people, with researchers paying little attention to various CNM styles. The current research elucidated differences among three styles of CNM: open relationships, polyamory, and swinging. Across three studies, we demonstrated that people in polyamorous or swinger-style relationships have higher levels of relationship satisfaction and other relational outcomes (e.g., passionate love, trust) than those in open relationships. That is, people in open relationships consistently fared more poorly in their relational outcomes than those in other types of CNM relationships. In Studies 4 and 5, we isolated some of the reasons for these differences. We found that differences in relational outcomes between open-style and other styles of CNM dissipated when controlling for (a) couples' approach to communication, (b) extrinsic versus intrinsic motivations for participating in CNM, (c) adherence to pro-monogamy beliefs and (d) degree of contact with one's partner's partners ("metamours"). Thus, CNM-specific relational dynamics are associated with dyadic adjustment in these relationships.

Motivations for Engaging in Consensually Non-Monogamous Relationships

Sexual, romantic, and intimate relationships provide opportunities for individual and interpersonal fulfillment and the enhancement of well-being. Though research has identified that consensual non-monogamy (CNM) offers unique relational benefits, little work has examined why individuals pursue CNM relationships. Both self-determination theory and self-expansion theory provide frameworks for understanding the range of intra- and interpersonal motives for choosing or negotiating a multipartnered relationship. We explored the reasons for which people engage in CNM and discuss how motivations for CNM might be linked to well-being and need fulfillment. Our study used a qualitative approach to examine the motivations individuals report for engaging in CNM relationships. As part of a larger online survey, participants completed open-ended questions examining motivations for, and experiences of, CNM relationships. Data from participants who indicated that they were currently in a CNM partnership was selected for the analyses (n = 540). Data were analyzed using thematic analysis, within a critical realist framework. Motivations were organized into six interconnected themes: reasons related to autonomy, beliefs and value systems, relationality, sexuality, growth and expansion, and pragmatism. Individuals reported diverse reasons for engaging in CNM relationships; reasons addressed both individual and relational needs and well-being. Findings contrast with stereotypic views of CNM relationships as unstable/unfulfilling or that individuals engage in CNM because of relationship problems. The findings may facilitate therapeutic interventions for counselors working with individuals who are in the process of negotiating or re-negotiating relationship boundaries.

What Drives the Dehumanization of Consensual Non-Monogamous Partners?

We built upon a recent study by Rodrigues, Fasoli, Huic, and Lopes (2018) by investigating potential mechanisms driving the dehumanization of consensual non-monogamous (CNM) partners. Using a between-subjects experimental design, we asked 202 Portuguese individuals (158 women; Mage = 29.17, SD = 9.97) to read the description of two partners in a monogamous, open, or polyamorous relationship, and to make a series of judgments about both partners. Results showed the expected dehumanization effect, such that both groups of CNM partners (open and polyamorous) were attributed more primary (vs. secondary) emotions, whereas the reverse was true for monogamous partners. Moreover, results showed that the dehumanization effect was driven by the perception of CNM partners as less moral and less committed to their relationship. However, these findings were observed only for individuals with unfavorable (vs. favorable) attitudes toward CNM relationship. Overall, this study replicated the original findings and extended our understanding of why people in CNM relationships are stigmatized.

Desire, Familiarity, and Engagement in Polyamory: Results From a National Sample of Single Adults in the United States

Coupledom and notions of intimacy and family formation with one committed partner are hallmarks of family and relationship science. Recent national surveys in the United States and Canada have found that consensually non-monogamous relationships are common, though prevalence of specific types of consensual non-monogamy are unknown. The present research draws on a United States Census based quota sample of single adults (N = 3,438) to estimate the prevalence of desire for, familiarity with, and engagement in polyamory-a distinct type of consensually non-monogamous relationship where people typically engage in romantic love and sexual intimacy with multiple partners. Results show that 1 out of 6 people (16.8%) desire to engage in polyamory, and 1 out of 9 people (10.7%) have engaged in polyamory at some point during their life. Approximately 1 out of 15 people (6.5%) reported that they knew someone who has been or is currently engaged in polyamory. Among participants who were not personally interested in polyamory, 1 out of 7 (14.2%) indicated that they respect people who engage in polyamory. Few sociodemographic correlates emerged; no differences in prevalence were found based on political affiliation, income, religion, geographic region, or race/ethnicity. Sexual minorities, men, and younger adults reported greater desire to engage in polyamory (compared to heterosexuals, women, and older adults, respectively). Men and people with lower education backgrounds were more likely to have previously engaged in polyamory (compared to women and people with higher education backgrounds, respectively). Given that emotional and sexual intimacy is an important part of most people's lives, understanding the varied ways in which people navigate their intimate lives is critical for the fields of relationship, sexuality, and family science.

A dyadic examination of self-determined sexual motives, need fulfillment, and relational outcomes among consensually non-monogamous partners

Intimate and sexual relationships provide opportunity for emotional and sexual fulfillment. In consensually non-monogamous (CNM) relationships, needs are dispersed among multiple partners. Using Self-Determination Theory (SDT) and dyadic data from 56 CNM partnerships (112 individuals), we tested how sexual motives and need fulfillment were linked to relational outcomes. We drew from models of need fulfillment to explore how sexual motives with a second partner were associated with satisfaction in the primary relationship. In a cross-sectional and daily experience study we demonstrated that self-determined reasons for sex were positively associated with sexual satisfaction and indirectly linked through sexual need fulfillment. Self-determined reasons for sex predicted need fulfillment for both partners at a three-month follow up. The association between sexual motives and need fulfillment was stronger on days when participants engaged in sex with an additional partner, though this was not related to satisfaction in the primary relationship. Implications for need fulfillment are discussed.

Fantasies About Consensual Nonmonogamy Among Persons in Monogamous Romantic Relationships

The present research explored fantasies about consensual nonmonogamous relationships (CNMRs) and the factors that predict such fantasies in a large and diverse online sample (N = 822) of persons currently involved in monogamous relationships. Nearly one-third (32.6%) of participants reported that being in some type of sexually open relationship was part of their favorite sexual fantasy of all time, of whom most (80.0%) said that they want to act on this fantasy in the future. Those who had shared and/or acted on CNMR fantasies previously generally reported positive outcomes (i.e., meeting or exceeding their expectations and improving their relationships). In addition, a majority of participants reported having fantasized about being in a CNMR at least once before, with open relationships being the most popular variety. Those who identified as male or non-binary reported more CNMR fantasies than those who identified as female. CNMR fantasies were also more common among persons who identified as anything other than heterosexual and among older adults. Erotophilia and sociosexual orientation were uniquely and positively associated with CNMR fantasies of all types; however, other individual difference factors (e.g., Big Five personality traits, attachment style) had less consistent associations. Unique predictors of infidelity fantasies differed from CNMR fantasies, suggesting that they are propelled by different psychological factors. Overall, these results suggest that CNMRs are a popular fantasy and desire among persons in monogamous romantic relationships. Clinical implications and implications for sexual fantasy research more broadly are discussed.

"How Do They Even Know They Love?" The Image of Polyamory in Polish Expert Discourse

The article presents the results of a thematic analysis of statements about polyamory made in the media by Polish psychology and sexology experts. The analysis was conducted on the basis of 20 pieces of material released in the Polish national press, radio, and television between July 2012 and October 2018. The results show that most of the analyzed experts approach polyamory with suspicion. In most cases, the decision to be in a polyamorous relationship is assessed very negatively, and in the eyes of the therapists it is evidence of psychological defects in people who make such attempts or it is seen as a harbinger of unfavorable outcomes for the relationship. This negative psychological evaluation is often accompanied by a strong moral assessment and a clear willingness to discourage society from this relationship model. The results show that representatives of psychology and medical sciences in the Polish media support and legitimize the social and moral order that promotes mono-normativity. The true reasons for the aforementioned negative assessment are hidden behind a veil of scientific objectivity.

Perceptions of monogamy, nonconsensual nonmonogamy and consensual nonmonogamy at the intersections of race and gender

Given the historical entrenchment of racialised stereotypes of Black women and Black men as sexually promiscuous, we wondered whether consensual nonmonogamy (CNM) among Black partners would be seen as favourably as among white partners. We also wondered if Black participants would perceive different relationship types differently from white participants. We pursued these questions in a vignette study featuring heterosexual couples coded as Black or as white and engaged in three different relationship types: monogamy, nonconsensual nonmonogamy (NCNM) and CNM. To facilitate comparisons across race*gender intersections, we used a sample comprising equivalent numbers of Black women, white women, Black men and white men aged 18-40. Contrary to expectations, analyses did not offer evidence of a racialised sexual double standard insofar as participant perceptions of relationship quality did not differ when considering a Black couple or a white couple. Indicating the persistence of mononormativity, participants across race*gender subsamples perceived monogamous relationships to be of higher quality, regardless of the vignette couple's race. We also found Black women, Black men and white women perceived CNM more favourably than NCNM, while there was no differentiation between CNM and NCNM among white men.

Preferences in Information Processing, Marginalized Identity, and Non-Monogamy: Understanding Factors in Suicide-Related Behavior among Members of the Alternative Sexuality Community

Suicide-related behavior (SRB) is a mental health disparity experienced by the alternative sexuality community. We assessed mental health, relationship orientation, marginalized identities (i.e., sexual orientation minority, gender minority, racial minority, ethnic minority, and lower education), and preferences in information processing (PIP) as factors differentiating lifetime SRB groups. An online cross-sectional survey study was conducted in 2018. Members of the National Coalition for Sexual Freedom (NCSF; n = 334) took part. Bivariate analyses identified the following SRB risk factors: female and transgender/gender non-binary identity, sexual orientation minority identity, lower education, suicide attempt/death exposure, Need for Affect (NFA) Avoidance, depression, and anxiety. Monogamous relationship orientation was a protective factor. Multi-nomial regression revealed the following: (1) monogamous relationship orientation was a protective factor for suicidal ideation and attempt; (2) lower education was a risk factor for suicide attempt; (3) anxiety was a risk factor for suicide attempt; and (4) depression was a risk factor for suicidal ideation. A two-way interaction showed that elevated NFA Approach buffered the negative impacts of depression. Relationship orientation, several marginalized identities (i.e., based on gender, sexual orientation, and educational level), and PIP all contributed uniquely to SRB. Further study is necessary to understand the role of relationship orientation with suicide. Health education and suicide prevention efforts with NCSF should be tailored to account for marginalized identity, mental health, and NFA factors.

Sexual Attitudes, Erotophobia, and Sociosexual Orientation Differ Based on Relationship Orientation

Consensual nonmonogamy (CNM) is an overarching term for relationship orientations that differ based on the degree to which consensual sexual and emotional needs are fulfilled outside of a dyad. Despite the diversity of CNM relationship orientations and growing research examining CNM, it is unclear whether the sexual attitudes, inclination to approach/avoid sexual stimuli (i.e., erotophobia-erotophilia), and sociosexuality differ among individuals who identify with distinct CNM relationships. Further, as the agreements made in CNM relationships permit extradyadic relationships, important differences might emerge for CNM and monogamous individuals. A convenience sample (N = 641) of individuals who self-identified as monogamous (n = 447), open (n = 80), polyamorous (n = 62), or swinger (n = 52) provided ratings of their sexual attitudes, erotophobia-erotophilia, and sociosexuality. Results indicated that swingers had the most permissive and instrumental attitudes, were the most erotophilic, and were the most unrestricted sexually. Conversely, monogamists scored the lowest on these traits. No differences emerged between relationship orientations for attitudes toward communion and birth control. These findings have important implications for sexuality research because they reinforce the view that some underlying differences and similarities exist between monogamous and CNM individuals.

Delineating the Boundaries Between Nonmonogamy and Infidelity: Bringing Consent Back Into Definitions of Consensual Nonmonogamy With Latent Profile Analysis

To gain insight into the mixed findings surrounding Consensual Nonmonogamy (CNM), this study developed the Triple-C model of commitment, conceptualizing relationship structures with three key dimensions: mutual consent, communication, and comfort. Latent profile analyses in an online sample (N = 1,658) identified five classes of relationship structures: two monogamous groups (68%; representing earlier- and later-stage relationships), CNM relationships (7.7%, marked by low interest in monogamy and high levels of mutual consent, comfort, and communication around commitment and EDSA), partially-open relationships (13%, with more mixed attitudes toward monogamy and lower consent, comfort, and communication), and one-sided EDSA relationships (11%, in which one partner desires monogamy while the other partner engages in EDSA with low levels of mutual consent, comfort, and communication). The monogamous and CNM groups demonstrated high levels of relationship and individual functioning, whereas the partially-open and one-sided nonmonogamous groups demonstrated lower functioning. These findings highlight the diversity of nonmonogamy that likely exists within self-report classifications like "swingers" and "open relationships," providing a possible explanation for the mixed findings in previous work. Decision tree analyses identified a 4-item algorithm (COMMIT4) that classifies individuals into these groups with 93% accuracy, offering a tool for incorporating relationship structure diversity in future work.

Life History and Multi-Partner Mating: A Novel Explanation for Moral Stigma Against Consensual Non-monogamy

Life history theory (LHT) predicts that individuals vary in their sexual, reproductive, parental, familial, and social behavior according to the physical and social challenges imposed upon them throughout development. LHT provides a framework for understanding why non-monogamy may be the target of significant moral condemnation: individuals who habitually form multiple romantic or sexual partnerships may pursue riskier, more competitive interpersonal strategies that strain social cooperation. We compared several indices of life history (i.e., the Mini-K, the High-K Strategy Scale, pubertal timing, sociosexuality, disease avoidance, and risk-taking) between individuals practicing monogamous and consensually non-monogamous (CNM) romantic relationships. Across several measures, CNM individuals reported a faster life history strategy than monogamous individuals, and women in CNM relationships reported earlier pubertal development. CNM individuals also reported more social and ethical risk-taking, less aversion to germs, and greater interest in short-term mating (and less interest in long-term mating) than monogamous individuals. From these data, we discuss a model to explain how moral stigma toward non-monogamy evolved and how these attitudes may be mismatched to the modern environment. Specifically, we argue that the culture of sexual ethics that pervades contemporary CNM communities (e.g., polyamory, swinging) may attenuate risky interpersonal behaviors (e.g., violent intrasexual competition, retributive jealousy, partner/child abandonment, disease transmission) that are relatively more common among those who pursue multi-partner mating.

Walk the Line: How Successful Are Efforts to Maintain Monogamy in Intimate Relationships?

Monogamy, typically defined as sexual and romantic exclusivity to one partner, is a near-universal expectation in committed intimate relationships in Western societies. Attractive alternative partners are a common threat to monogamous relationships. However, little is known about how individuals strive to protect their relationships from tempting alternatives, particularly those embedded in one's social network. The current exploratory study was guided by the Investment Model, which states that satisfaction, investments, and perceived alternatives to a relationship predict commitment, which in turn predicts relationship longevity. The study aimed to identify relationship and extradyadic attraction characteristics associated with monogamy maintenance efforts, specifically relationship commitment, as predicted by the Investment Model. The efficacy of monogamy maintenance efforts was assessed via sexual and emotional infidelity measures at a 2-month follow-up. U.S. adults in heterosexual intimate relationships (N = 287; 50.2% male; M age = 34.5 years; M relationship length = 87 months) were recruited online to complete the survey study. Through structural equation modelling, the Investment Model structure was replicated, and relationship commitment predicted use of relationship-enhancing efforts as well as self-monitoring/derogation efforts. Individuals who experienced reciprocated attraction used significantly more avoidance and self-monitoring/derogation efforts than did those who experienced unreciprocated attraction. Ultimately, monogamy maintenance efforts did not significantly predict success in maintaining monogamy at follow-up. These findings have important research, educational, and clinical implications relating to relationship longevity.

Comparing Relationship Quality Across Different Types of Romantic Partners in Polyamorous and Monogamous Relationships

Polyamory is the practice of having multiple emotionally close relationships that may or may not be sexual. Research concerning polyamory has just begun to determine how relationships among partners in polyamorous arrangements may vary. Most of the research assessing perceptions of polyamorous partners has focused on primary-secondary configurations; however, non-hierarchical configurations exist and can involve having multiple primary partners or having only non-primary partners. The current research is the first to examine perceptions of partners and relationship quality in various polyamorous configurations and compares results for each configuration to monogamous partners. Results from online convenience samples suggest that co-primary and non-primary configurations are common among polyamorous participants, with approximately 38% identifying with one of these configurations in 2013 and 55% in 2017. Furthermore, our results suggest that while relationships with partners in co-primary and non-primary structures still differ in some ways (e.g., investment, acceptance, secrecy, time spent having sex), they are closer to their ideals on several psychologically meaningful indicators of relationship quality (e.g., commitment and satisfaction). In other words, despite rejecting hierarchical primary-secondary labels, many of the same relationship qualities differ systematically among partners in non-hierarchical relationships. Furthermore, pseudo-primary partners and primary partners in these relationships are more comparable to monogamous partners than they are to secondary partners. We discuss how these results inform our understanding of polyamorous and monogamous relationships and suggest future directions based on these findings.

Sociosexual Attitudes and Quality of Life in (Non)Monogamous Relationships: The Role of Attraction and Constraining Forces Among Users of the Second Love Web Site

Research has typically shown that unrestricted sociosexuality is negatively associated with relationship quality and that relationship quality is positively associated with quality of life (QoL). However, these findings may be restricted to individuals in monogamous relationships, especially those with prior extradyadic interactions (i.e., non-consensual non-monogamous; NCNM). Indeed, individuals in consensual non-monogamous (CNM) relationships have more unrestricted sociosexuality and are also more satisfied with and committed to their relationships. Still, little research has examined whether both relationship agreements are associated differently with attraction forces (wanting to be) and constraining forces (having to be) in the relationship and how they are related to QoL. We conducted a cross-sectional study with 373 heterosexuals (73.2% men, M_age = 41.15, SD = 10.18) registered on Second Love, a dating Web site for romantically involved individuals. Results showed differences in the hypothesized model, according to relationship agreement. For individuals in CNM relationships, unrestricted sociosexuality was associated with stronger attraction forces, which were then associated with greater QoL. The opposite pattern was found for those in NCNM relationships. Furthermore, and regardless of relationship agreement, unrestricted sociosexuality was associated with weaker constraining forces, which were associated with greater QoL. These results make a novel contribution to the literature on relationship agreements and how they relate to QoL.

Open Relationship Prevalence, Characteristics, and Correlates in a Nationally Representative Sample of Canadian Adults

Open relationships are those in which individuals agree to participate in sexual and/or emotional and romantic interactions with more than one partner. Accurate estimates of the prevalence of open relationships, based on representative, unbiased samples, are few, and there are none from outside of the United States. We present findings from a nationally representative sample of 2,003 Canadian adults, administered in 2017 via an online questionnaire. Overall, 2.4% of all participants, and 4.0% of those currently in a relationship, reported currently being in an open relationship. One-fifth of participants reported prior engagement in an open relationship, and 12% reported open as their ideal relationship type. Men, compared with women, were more likely to report prior open relationship engagement and to identify open as their ideal relationship type. Younger participants were more likely both to engage in and to prefer open relationships. Relationship satisfaction did not differ significantly between monogamous and open relationships. Having a match between one's actual relationship type and one's preferred relationship type was associated with greater relationship satisfaction. Findings suggest that, while currently only a small proportion of the population is in an open relationship, interest in open relationships is higher, particularly among younger adults, and open appears to be a viable and important relationship type.

Trust, Sexual Trust, and Sexual Health: An Interrogative Review

Trust is experienced almost constantly in all forms of social and interpersonal relationships, including sexual relationships, and may contribute both directly and indirectly to sexual health. The purpose of this review is to link three aspects of trust to sexual health: (1) the role of trust in sexual relationships; (2) the role of trust in sexually transmitted infection (STI) prevention, particularly condom use; and (3) the relevance of trust in sexual relationships outside of the traditional model of monogamy. The review ends with consideration of perspectives that could guide new research toward understanding the enigmas of trust in partnered sexual relations in the context of sexual and public health.

Expanding Statistical Frontiers in Sexual Science: Taxometric, Invariance, and Equivalence Testing

Sexual scientists must choose from among myriad methodological and analytical approaches when investigating their research questions. How can scholars learn whether sexualities are discrete or continuous? How is sexuality constructed? And to what extent are sexuality-related groups similar to or different from one another? Though commonplace, quantitative attempts at addressing these research questions require users to possess an increasingly deep repertoire of statistical knowledge and programming skills. Recently developed open-source software offers powerful yet accessible capacity to researchers wishing to perform strong quantitative tests. Taking advantage of these new statistical opportunities will require sexual scientists to become familiar with new analyses, including taxometric analysis, tests of measurement variability and differential item functioning, and equivalence testing. In the current article, I discuss each of these analyses, providing conceptual and historical overviews. I also address common misunderstandings for each analysis that may discourage researchers from implementing them. Finally, I describe current best practices when using each analysis, providing reproducible coding examples and interpretations along the way, in an attempt to reduce barriers to the uptake of these analyses. By aspiring to explore these new statistical frontiers in sexual science, sexuality researchers will be better positioned to test their substantive theories of interest.

Queer Intimacies: A New Paradigm for the Study of Relationship Diversity

Recognition of sexual and gender diversity in the 21st century challenges normative assumptions of intimacy that privilege heterosexual monogamy and the biological family unit, presume binary cisgender identities, essentialize binary sexual identities, and view sexual or romantic desire as necessary. We propose a queer paradigm to study relationship diversity grounded in seven axioms: intimacy may occur (1) within relationships featuring any combination of cisgender, transgender, or nonbinary identities; (2) with people of multiple gender identities across the life course; (3) in multiple relationships simultaneously with consent; (4) within relationships characterized by consensual asymmetry, power exchange, or role-play; (5) in the absence or limited experience of sexual or romantic desire; (6) in the context of a chosen rather than biological family; and (7) in other possible forms yet unknown. We review research on queer relational forms, including same-sex relationships; relationships in which one or more partners identify as transgender, gender nonbinary, bisexual, pansexual, sexually fluid, "mostly" straight, asexual, or aromantic; polyamory and other forms of consensual nonmonogamy; kink/fetish relationships; and chosen families. We argue that a queer paradigm shifts the dominant scientific conception of relationships away from the confines of normativity toward an embrace of diversity, fluidity, and possibility.

Changes in the swinging lifestyle: a US national and historical comparison

Although engaging in extramarital relationships with permission from spouses has been practised for generations, relatively little is known about those who participate and how they have changed over the years. This study expands on existing research by comparing the demographics and sexual practices of those in swinging and non-swinging communities from the 1980s to those in 2016. Data from the 1980s were collected through membership forms submitted to a swinger organisation and a national dataset conducted in the USA (i.e. The General Social Survey), while the recent dataset was collected through an online survey. Compared to the non-swinging population, swingers were more likely to be Caucasian, younger, educated, wealthy and more satisfied with their marriage and sex life. Demographic comparisons of swingers from 1982 to 2016 showed an increase in diversity, growing connection to the US Democratic Party and increased use of protection to avoid sexually transmitted diseases. Marital satisfaction remained the same regardless of year measured, but the amount of sex engaged in over a year decreased over time.
