The association of an open relationship orientation with health and happiness in a sample of older US adults

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.

Polygamous Interest in a Mononormative Nation: The Roles of Sex and Sociosexuality in Polygamous Interest in a Heterosexual Sample from the UK

Polygamy is a form of "one-sided" consensually non-monogamous relationship where one person has multiple committed partners, each of whom is only involved with that one person. It was likely a reoccurring feature of ancestral mating that posed adaptive problems for our ancestors. Yet polygamy, and multi-partnering more generally, is understudied in Western cultures, raising questions about the existence of polygamous interest and whether this is calibrated adaptively to personal conditions. In two studies, we examined polygamous interest in two heterosexual online samples from the UK. In Study 1 (N = 393), modest interest was found for polygamous relationships overall. Men were six times more open to polygyny than women, but there was little sex difference in openness to polyandry. Further analysis revealed that all forms of multi-partnering were undesirable relative to singlehood and monogamy; however, consensual multi-partner relationships were less undesirable than non-consensual ones. Sex differences were largest for polygyny and arrangements where men had agreed access to a casual partner alongside a committed one, yet these were two of the most acceptable forms of multi-partnering when men and women's responses were combined. Sociosexuality positively predicted interest in most forms of multi-partnering. Study 2 (N = 735) focused on polygyny and added status-linked traits as predictors. The results of Study 1 were broadly replicated, though the status-linked traits did not predict polygynous interest specifically. Instead, sociosexuality and male intrasexual competitiveness uniquely predicted general interest in multi-partner relationships. Overall, interest in polygamy appears to emerge despite social discouragement and sex differences in interest track the relative costs and benefits associated with it. However, there is no strong evidence that polygamous interest is uniquely calibrated to personal conditions when compared to other forms of multi-partnering.

Defining Polyamory: A Thematic Analysis of Lay People's Definitions

This study aimed to analyze laypeople's definitions of polyamory and compare definitions presented by people who are not willing to engage in consensual non-monogamy (CNM) and those who are or are willing to be in a CNM relationship. This exploratory qualitative study used data collected from a convenience sample through a web survey, where people answered the question "What does polyamory mean?" We conducted thematic analysis to examine patterns in meaning and used demographic data to compare themes among groups. The final sample comprised 463 participants aged 18-66 years (M = 32.19, SD = 10.02), mostly heterosexual (60%). Of the total sample, 54% were in a monogamous relationship, followed by 21% not in a relationship, and 13% in a non-monogamous relationship. Analysis showed that people define polyamory mostly as a set of behaviors in a relationship, followed by the potential of multiple relationships or feelings for multiple people. Definitions also include emotional, sexual, and ethical aspects. People in CNM relationships are more likely to define polyamory as constituting a potential form of relating, focus more on interpersonal feelings and ethics, and include consent in their definitions than those unwilling to engage in CNM. People in CNM relationships also focus particularly on the non-central role of sex within these relationships, which might challenge assumptions about sexuality in these relationships in clinical and research settings.

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.

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.

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.

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.

Perceived sexual self-control and condom use with primary and casual sex partners: age and relationship agreement differences in a Portuguese sample

OBJECTIVE

Consistent condom use is still not ideal. Research showed that perceived sexual self-control is associated with greater likelihood of using condoms. However, this association seems to vary according to age and relationship agreement (i.e. non-consensual non-monogamy, NCNM vs. consensual non-monogamy, CNM).

DESIGN

Cross-sectional study with 307 heterosexual users of a dating web site for romantically involved individuals (81.8% men; M_age = 42.24, SD = 9.65, range: 23-76 years). All individuals were in a romantic relationship (M_length = 13.47 years, SD = 9.39).

MEASURES

Demographic information, perceived sexual self-control, condom use frequency (casual sex partners; primary partner in the last 3 months) and relationship agreement.

RESULTS

Independently of relationship agreement, perceived sexual self-control was positively associated with condom use frequency with casual sex partners among younger and middle age participants, but not older ones (>49 years). Regarding the primary partner, a similar pattern emerged for CNM participants. In contrast, no significant association between perceived sexual self-control and condom use frequency with the primary partner emerged for NCNM individuals, regardless of age.

CONCLUSION

Our findings can inform evidence-based strategies to promote consistent condom use as an effective behaviour to prevent sexually transmitted infections, especially among older and NCNM individuals.

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.

Rethinking Risk, Culture, and Intervention in Collective Sex Environments

This article provides a narrative overview of research on HIV/STI risk and collective sexual behavior based on an inclusive analysis of research on environments where people gather for sexual activity-sex clubs, swingers' clubs, bathhouses, parks, private sex parties, etc. The aim is to analyze how collective sex has been approached across disciplines to promote conversation across paradigms and suggest new lines of inquiry. Attention to context-such as the location of sex-was a necessary redress to universalizing models of sexual risk-taking behavior, leading to insights rooted in the particularities of each environment and its users. However, the identification of ever more precise risk groups or environmental idiosyncrasies eventually becomes theoretically restrictive, leading to an overestimation of the uniqueness of sexual enclaves, and of the difference between any given enclave and the broader social milieu. Using a theoretical framework of transgression to interpret the interdisciplinary literature, similarities in the spatial and social organization of collective sex environments are identified. Insights generated from this complementary perspective are then applied to understandings of collective sex: first, the example of male-female (MF) "swingers" is used to illustrate the need to establish, rather than assume, the distinctiveness of each non-normative sexual enclave, and to broaden the conceptualization of context; second, questions are raised about the practicality of interventions in collective sex environments. Finally, new lines of intellectual inquiry are suggested to shed light not just on collective sex but on sociosexual issues more generally, such as increasing protective sexual health behavior or negotiating consent in sexual encounters.

Caught in a "Bad Romance"? Reconsidering the Negative Association Between Sociosexuality and Relationship Functioning

Sociosexuality refers to individual differences in interest and willingness to engage in sexual activity without an emotional connection. Unrestricted sociosexuality is associated with a greater likelihood of infidelity and with poorer relationship quality. However, previous research has failed to examine relationship-specific characteristics that may moderate these findings. Two studies of romantically involved adults examined whether relationship commitment and different relationship agreement types moderate the associations between unrestricted sociosexuality and infidelity. Study 1 (N = 300) showed that individuals in consensual monogamous (CM) relationships with extradyadic sex (EDS) experiences were more sociosexually unrestricted than individuals without such experiences. The positive association between unrestricted sociosexuality and EDS emerged only for less, but not more, committed individuals. Study 2 (N = 270) replicated these results. Furthermore, results showed that individuals in consensual nonmonogamous relationships (CNM) relationships were the most sociosexually unrestricted, but no differences emerged in relationship commitment or satisfaction, when compared to individuals in CM relationships without prior EDS. Individuals in CM relationship with prior EDS were the least committed and satisfied. The negative association between unrestricted sociosexuality and both relationship quality indicators emerged for all individuals in CM relationships, but it was nonsignificant for individuals in CNM relationships. Implications are discussed.

Investigation of Consensually Nonmonogamous Relationships

We proposed that the premise that monogamy is the exemplary form of romantic partnership underlies much theory and research on relationship quality, and we addressed how this bias has prompted methodological issues that make it difficult to effectively address the quality of nonmonogamous relationships. Because the idea that consensually nonmonogamous (CNM) relationships are functional (i.e., satisfying and of high quality) is controversial, we included a basic study to assess, in a variety of ways, the quality of these relationships. In that study, we found few differences in relationship functioning between individuals engaged in monogamy and those in CNM relationships. We then considered how existing theories could help researchers to understand CNM relationships and how CNM relationships could shed light on relationship processes, and we proposed a model of how CNM and monogamous relationships differ. Finally, in a second study, we determined that even researchers who present data about CNM are affected by the stigma surrounding such relationships. That is, researchers presenting findings favoring polyamory were perceived as more biased than researchers presenting findings favoring monogamy.
