The Demography of Asexuality

Patterns of Genital and Subjective Sexual Arousal in Cisgender Asexual Men

Human asexuality has been defined as a lack of sexual attraction to others, although its nature is not well understood. Asexual men's genital and subjective sexual arousal patterns were compared to sexual men's to better understand asexual men's sexual response patterns. Using a penile plethysmograph to measure genital arousal, 20 asexual, 27 heterosexual, and 22 gay cisgender men (M age = 28.28, SD = 9.41) viewed erotic films depicting sexual activity or masturbation, and a subsample engaged in sexual fantasy of their choosing. Questionnaires assessing sexual function and behavior were also completed. Asexual men scored lower on sexual desire and orgasmic function, higher on sexual aversion, and did not differ on overall sexual satisfaction. Compared with gay and heterosexual men, asexual men demonstrated lower genital and subjective sexual arousal to the erotic films but displayed similar sexual arousal when engaging in sexual fantasy. Asexual men's lower levels of sexual excitation rather than their higher levels of sexual inhibition were associated with lower responses to the erotic films. These findings suggest asexual men have preferred sexual stimuli that differ from sexual men and have a similar capacity for sexual arousal as sexual men. Collectively these findings add to a growing literature aiming to understand the nature of asexuality.

Asexuality, Graysexuality, and Demisexuality: Distinctions in Desire, Behavior, and Identity

As identities within the ace spectrum gain greater visibility in describing those who experience limited or no sexual attraction, it is vital to understand points of commonality and distinction among individuals who identify as asexual, graysexual, and demisexual. Among respondents to the Ace Community Survey, a large international sample of individuals who identify on the ace spectrum, we found that those who identified as asexual (n = 9,476, M_age = 22.3, 61.0% female, 12.5% male), graysexual (n = 1,698, M_age = 24.2, 58.8% female, 16.5% male), or demisexual (n = 1,442, M_age = 24.2, 62.8% female, 12.6% male) varied in indicators related to sexual desire, behavior, and identity. Asexual individuals were the least likely to be in a relationship, experience romantic attraction, or identify with orientation labels signifying genders of attraction such as straight, bisexual, heteroromantic, and biromantic. Asexual individuals were the most likely to identify as aromantic, graysexual individuals the most likely to identify as grayromantic, and demisexual individuals the most likely to identify as demiromantic. Asexual individuals also scored the lowest on measures of sex drive, personal disposition toward engaging in sex, and masturbation frequency, with graysexual individuals scoring lower than demisexual individuals on the first two.

Stability and Change in Asexuality: Relationship Between Sexual/Romantic Attraction and Sexual Desire

This study examined the stability and change in asexuality in terms of sexual orientation identity, sexual/romantic attraction, and sexual desire. Data were collected in three waves at 12-month intervals (n = 168). In each wave, the participants completed measures of sexual/romantic orientation identity, sexual/romantic attraction, the Sexual Desire Inventory, and the Asexuality Identification Scale (AIS). Approximately 83% of asexual and gray-asexual individuals maintained their sexual orientation identity between two adjacent waves. The latent growth models indicated an increased tendency for sexual/romantic attraction and solitary sexual desire, while a decreased tendency for AIS over time was established. Only the sexual attraction slope significantly predicted asexual identity, indicating a longitudinal effect of sexual attraction on asexual identification. Initial levels of sexual attraction, and scores on the AIS and dyadic sexual desire (DSD) were associated with stability and changes in asexual identity. Asexual individuals who reported low sexual attraction, low DSD, and high AIS maintained their asexual identity, whereas those who reported high sexual attraction, high DSD, and low AIS were more likely to change their sexual orientation. The current findings indicate the relative stability of asexuality, which supports the notion that asexuality could be deemed a fourth sexual orientation.

Are Autism Spectrum Disorder and Asexuality Connected?

Asexuality is a lack of sexual attraction to any gender. There is some evidence to suggest that many self-identified asexuals have a formal diagnosis of autism spectrum disorder which is characterized by deficits in social interaction and communication, as well as by restricted and repetitive interests and behaviors. Additionally, the literature shows that asexuality and lack of sexual attraction or low sexual interest is overrepresented in people with autism spectrum disorder compared with neurotypical samples. Nevertheless, no studies have been conducted to investigate the relationship between autism and asexuality in depth. We conducted a systematic review of the literature to examine whether asexuality and autism spectrum disorder are connected. We conclude that asexuality and autism share various aspects, such as a possible role of prenatal factors, reference to romantic dimensions of sexual attraction and sexual orientation, and non-partner-oriented sexual desire, but future research should explore and clarify this link.

Beyond the Label: Asexual Identity Among Individuals on the High-Functioning Autism Spectrum

Researchers have suggested that asexuality, which has been conceptualized traditionally as a persistent lack of sexual attraction to others, may be more common among individuals with autism spectrum disorder than in the neurotypical population. However, no studies to date have considered how these individuals understand and conceptualize their sexual identity. The aim of this study was to provide a more nuanced understanding of asexuality among individuals with high-functioning autism spectrum disorder (HF-ASD) than has been done in the past. Individuals with ASD, 21-72 years old (M = 34.04 years, SD = 10.53), were recruited from online communities that serve adults with ASD and Amazon's Mechanical Turk to complete an online survey of sexual and gender identity. Overall, 17 (5.1%) participants who met study criteria (N = 332) self-identified as asexual. However, 9 of the 17 people identifying as asexual expressed at least some sexual attraction to others. In addition, based on open-ended responses, some participants linked their asexual identity more with a lack of desire or perceived skill to engage in interpersonal relations than a lack of sexual attraction. Results suggest that researchers should be cautious in attributing higher rates of asexuality among individuals with ASD than in the general population to a narrow explanation and that both researchers and professionals working with individuals with ASD should consider multiple questions or approaches to accurately assess sexual identity.

Asexual Identity, Personality, and Social Motivations in a New Zealand National Sample

Growing research interest in asexuality has led to several notable findings around the differences between asexual people and those with other sexual orientations. These findings have recently extended to personality, but questions remain around differences in personality between asexual people and others. Furthermore, qualitative and quantitative research disagrees about whether asexual people are less interested in close relationships than others. This paper used data from a nationally representative sample of self-identified asexual participants (Analysis 1: n_women = 216, n_men = 54, n_{gender diverse} = 13; Analysis 2: n_women = 53, n_men = 19, n_{gender diverse} = 3) and matched samples of heterosexual and lesbian, gay, and bisexual/plurisexual (LGB) participants (N's = 75-283) drawn from the New Zealand Attitudes and Values Study (Ns = 19,396-54,183) to explore personality (Analysis 1) and approach and avoidance social motivations (Analysis 2). Compared to heterosexuals, asexual participants reported significantly lower extraversion, agreeableness, and conscientiousness, and higher emotionality, openness, and honesty-humility. Compared to those who identified as LGB, asexual participants reported significantly lower extraversion and agreeableness and higher honesty-humility. In addition, asexual participants scored significantly lower on approach (but not avoidance) social motivation than both heterosexual and LGB participants, indicating that they are less motivated to enhance positive experiences and behavior in their social relationships. These results help to clarify how personality and social motivations covary with sexual identity.

Ace and Aro: Understanding Differences in Romantic Attractions Among Persons Identifying as Asexual

First characterized by Kinsey in 1948, asexuality can be broadly defined as an absence of sexual attraction, with approximately 1% of the population identifying as asexual. While asexuality research has flourished recently, very few papers have investigated the unique mechanism of romantic attraction in asexual people, notably that some experience romantic attraction (romantic asexual) while others do not (aromantic asexual). This study compared romantic and aromantic asexual individuals through secondary data analysis on demographic, behavioral, psychological, and physiological measures as the primary objective and compared asexual people to allosexual people on some measures as a secondary aim. After combining data from seven previous asexuality studies (n = 4032 total), we found that 74.0% of asexual people reported experiencing romantic attraction. No significant difference was found in distribution of men and women between the aromantic and romantic asexual groups, though the asexual group showed higher proportions of women and non-binary genders compared to the allosexual comparison group. Romantic asexual participants reported a diverse range of romantic orientations, with only 36.0% reporting a heteroromantic orientation, compared to 76.2% of allosexual participants. As predicted, romantic asexual individuals were more likely to have been in a relationship when completing the survey, reported more past romantic and sexual partners and more frequent kissing than aromantic asexual people, and experienced more partner-oriented sexual desire than the aromantic asexual group. There were also differences in personality as romantic asexual people were less cold, more nurturant, and more intrusive than the aromantic asexual group. No difference was seen between romantic and aromantic asexual individuals in demographic characteristics, likelihood of having children, solitary sexual desire, physiological sexual functioning, frequencies of masturbation and sexual fantasy, or depression. These similarities and differences between romantic and aromantic asexual people highlight the diversity within the asexual community.

Understanding Alcohol and Tobacco Consumption in Asexual Samples: A Mixed-Methods Approach

Existing research suggests significant differences in alcohol and tobacco consumption trends according to one's sexual orientation. However, asexual people have not yet been included in these comparisons. In this mixed-methods, two-part study, we sought to compare group differences in alcohol and tobacco consumption among sexual orientations, focusing on asexual people, sexual people, and those in the "gray" area between asexual and sexual (i.e., "gray-asexual"). Data for Study 1 came from four British studies: National Surveys of Sexual Attitude and Lifestyles I, II, and III in 1990, 2000, and 2010 (NATSAL I, II, III) and Towards Better Sexual Health (TBSH) in 2000. Sample sizes for each study by gender are: NATSAL I-M: 1923 F: 3511; NATSAL II-M: 4604 F: 6031; NATSAL III-M: 6122 F: 7966; TBSH-M: 347 F: 552. Notably, asexual and gray-asexual respondents were found to consume significantly less alcohol and were more likely to abstain from drinking alcohol altogether, compared to allosexual respondents. Differences in tobacco consumption were only statistically significant for asexual respondents in two of three studies that included tobacco consumption. Each of the four studies also found that asexual and gray-asexual respondents were more likely to be non-drinkers (40.0-77.8%, asexual and 28.1-50.1% gray-asexual, non-drinkers, respectively) than allosexual respondents (10.2-27.2%, non-drinkers). Interviews conducted in Study 2 identified somatic, social, and psychological experiences and motivations that may shed light on the reasons for lower drinking frequencies among asexual individuals. Variability in alcohol consumption levels among asexual, lesbian, gay, and bisexual respondents, and the general population raises new questions about the motivations for why people consume alcohol.

Personality and Sexual Orientation: Extension to Asexuality and the HEXACO Model

Previous research has examined self-identified sexual orientation in relation to self-reports on the Big Five personality factors. Here we extend this research by including asexuality as a fourth sexual orientation and by assessing the HEXACO personality factors, using self-report data from a large anonymous online sample (N ≈ 100,000). A large overlap was observed among all sexual orientation groups on all six HEXACO dimensions, but notable group differences also emerged. All nonheterosexual groups, particularly bisexual people, averaged higher in openness to experience than did heterosexuals. Heterosexual men averaged much lower in emotionality than heterosexual women, but only a small difference was observed between gay men and lesbians on this dimension. Asexual men and women averaged lower in extraversion and in some facets of emotionality (specifically, dependence and sentimentality) than did the other sexual orientation groups of the same sex. Results are discussed in relation to the different social realities that each sexual orientation group often experiences, along with the (gender-related) developmental influences hypothesized to underlie in part the origins of sexual orientation.

Patterns of Asexuality in China: Sexual Activity, Sexual and Romantic Attraction, and Sexual Desire

This study examined patterns of asexuality in Chinese asexual people in terms of sexual activities, sexual/romantic attraction, and sexual desire. The sample included 227 (64 men and 163 women) asexual participants and 57 (26 men and 31 women) uncertain asexual participants recruited from social networks for asexual people. The control group included 217 (115 men and 102 women) heterosexual participants recruited from general social networks. Participants scoring 40 or higher on the Asexuality Identification Scale were classified as asexual. Asexual participants reported having less frequent masturbation, sexual intercourse experience, and sexual and romantic attraction compared to heterosexual participants. Lower sexual attraction among asexuals indicated that "people who experience little or no sexual attraction" would be a more appropriate definition of asexuality. The pattern of uncertain asexual participants' sexual/romantic attraction and sexual desire was intermediate between heterosexual and asexual participants. Asexual participants scored significantly lower on dyadic sexual desire and slightly lower on solitary sexual desire than heterosexual participants. There were significant differences in sexual activities and solitary sexual desire among romantic orientation categories. Homoromantic participants showed higher dyadic sexual desire and were more likely to engage in masturbation, indicating the heterogeneity among asexual people. The findings indicated that Chinese asexual people showed similar patterns of asexuality as in Western nations. Specifically, asexual people have little or no sexual attraction, non-partner-orientated sexual desire, and are heterogeneous in sexual activities and sexual desire. This implies similar mechanisms underlying the etiology of asexuality across cultures.

Asexual Identity in a New Zealand National Sample: Demographics, Well-Being, and Health

Academic interest in asexuality has increased in recent years; however, there is yet to be a national probability study exploring the correlates of self-identifying as asexual. Here, we utilized data from the 2014/15 New Zealand Attitudes and Values Study. Past research has typically used attraction-based measures; however, we asked participants to describe their sexual orientation using a self-generated, open-ended item, and 0.4% (n = 44) self-identified as asexual. We then compared self-identified asexual participants with a heterosexual reference group (n = 11,822) across a large number of demographic, psychological, and health variables. Relative to heterosexuals, self-identified asexual participants were (1) more likely to be women, and (2) substantially less likely to be cisgender, (3) in a serious romantic relationship, or (4) a parent. No deleterious mental or physical health effects were associated with asexuality when compared to heterosexuality. This study provides the first attempt at measuring self-identification as asexual in a national sample and highlights core similarities and differences between those who identify as asexual and heterosexual.

The Diversity and Prevalence of Sexual Orientation Self-Labels in a New Zealand National Sample

In this study, we asked participants to "describe their sexual orientation" in an open-ended measure of self-generated sexual orientation. The question was included as part of the New Zealand Attitudes and Values Study (N = 18,261) 2013/2014 wave, a national probability survey conducted shortly after the first legal same-sex marriages in New Zealand. We present a two-level classification scheme to address questions about the prevalence of, and demographic differences between, sexual orientations. At the most detailed level of the coding scheme, 49 unique categories were generated by participant responses. Of those who responded with the following, significantly more were women: bisexual (2.1 % of women, compared to 1.5 % of men), bicurious (0.7 % of women, 0.4 % of men), and asexual (0.4 % of women and less than 0.1 % of men). However, significantly fewer women than men reported being lesbian or gay (1.8 % of women, compared to 3.5 % of men). Those openly identifying as bicurious, bisexual, or lesbian/gay were significantly younger than those with a heterosexual orientation. This study shows diversity in the terms used in self-generated sexual orientations, and provides up-to-date gender, age, and prevalence estimates for the New Zealand population. Finally, results reveal that a substantial minority of participants may not have understood the question about sexual orientation.

Sexual Fantasy and Masturbation Among Asexual Individuals: An In-Depth Exploration

Human asexuality is generally defined as a lack of sexual attraction. We used online questionnaires to investigate reasons for masturbation, and explored and compared the contents of sexual fantasies of asexual individuals (identified using the Asexual Identification Scale) with those of sexual individuals. A total of 351 asexual participants (292 women, 59 men) and 388 sexual participants (221 women, 167 men) participated. Asexual women were significantly less likely to masturbate than sexual women, sexual men, and asexual men. Asexual women were less likely to report masturbating for sexual pleasure or fun than their sexual counterparts, and asexual men were less likely to report masturbating for sexual pleasure than sexual men. Both asexual women and men were significantly more likely than sexual women and men to report that they had never had a sexual fantasy. Of those who have had a sexual fantasy, asexual women and men were significantly more likely to endorse the response "my fantasies do not involve other people" compared to sexual participants, and consistently scored each sexual fantasy on a questionnaire as being less sexually exciting than did sexual participants. When using an open-ended format, asexual participants were more likely to report having fantasies about sexual activities that did not involve themselves, and were less likely to fantasize about topics such as group sex, public sex, and having an affair. Interestingly, there was a large amount of overlap between sexual fantasies of asexual and sexual participants. Notably, both asexual and sexual participants (both men and women) were equally likely to fantasize about topics such as fetishes and BDSM.

Asexuality: what it is and why it matters

In this review article, human asexuality, a relatively understudied phenomenon, is discussed. Specifically, definitions and conceptualizations of asexuality (e.g., is it a unique category of sexual orientation?), biological and historical contexts, identity issues, discrimination against asexual people relative to other minorities, origins, and variations, including gender differences, are reviewed. Whether asexuality should be construed as a disorder is also discussed. The study of asexuality allows for a better understanding of an underrecognized sexual minority but also affords a unique opportunity to examine and better understand human sexuality.

Sexual fantasy and masturbation among asexual individuals

Human asexuality is defined as a lack of sexual attraction, and research suggests that it may be best conceptualized as a sexual orientation. Sexual fantasies are thought to be universally experienced and are often understood to represent true sexual desire more accurately than sexual behaviour. We investigated the relationship between asexuality, masturbation and sexual fantasy as part of a larger online study. Self-identified asexual individuals were compared to sexual individuals with and without low sexual desire. A total of 924 individuals (153 men, 533 women, and 238 individuals who did not respond to the query about sex) completed online questions asking about masturbation and sexual fantasy. Five hundred thirty four were classified in the asexual group, 87 met diagnostic criteria for hypoactive sexual desire disorder (HSDD), 78 met criteria for subthreshold HSDD without distress, and 187 were a sexual comparison group (i.e., identified as sexual, and had no reported difficulties in sexual desire or distress). Asexual individuals were significantly less likely to have masturbated in the past month and significantly more likely to report never having had a sexual fantasy. Specifically, 40% of asexual participants reported never having had a sexual fantasy compared to between 1% and 8% of participants in the sexual groups. Eleven percent of asexual individuals reported that their sexual fantasies did not involve other people, compared to 1.5% of all sexual individuals. Taken together, these findings suggest that there are notable differences in patterns of sexual fantasy between asexual individuals and sexual individuals with and without low sexual desire.
