Intersexual and Intrasexual Differences in Mate Selection Preferences Among Lesbian Women, Gay Men, and Bisexual Women and Men

Sex differences in mating strategies and partner preferences are well established. However, most research solely focused on heterosexual women and men. We examined the mate selection, marriage, and age preferences of a sample of lesbian women, gay men, and bisexual women and men (LGB) who took part in an online dating survey. Additionally, we analyzed inter- and intrasexual differences in these preferences. A total of 710 participants rated the importance of 82 mate selection criteria and 10 marriage criteria, and they also indicated their age preferences and short-term and long-term relationship orientation. An exploratory factor analysis suggested 11 relevant domains of mate selection in the LGB sample, with sex, age, and long-term relationship orientation being relevant predictors of differences in these domains. We compared the LGB data with data collected from 21,245 heterosexual women and men on the same mate selection criteria. Results showed that the participants' sex was the most important predictor of differences in mate selection and marriage preferences, while intrasexual variables (sexual orientation and relationship orientation) explained only a small part of the variance. We incorporated the results into the current discussion about partner preferences and sexual orientation.

The Link Between Age and Partner Preferences in a Large, International Sample of Single Women

Women's capacity to reproduce varies over the life span, and developmental goals such as family formation are age-graded and shaped by social norms about the appropriate age for completing specific developmental tasks. Thus, a woman's age may be linked to her ideas about what an ideal partner should be like. With the goals of replicating and extending prior research, in this study we examined the role of age in women's partner preferences across the globe. We investigated associations of age with ideal long-term partner preferences in a cross-cultural sample of 17,254 single (i.e., unpartnered) heterosexual women, ages 18 to 67, from 147 countries. Data were collected via an online questionnaire, the Ideal Partner Survey. Confirming our preregistered hypotheses, we found no or only negligible age effects on preferences for kindness-supportiveness, attractiveness, financial security-successfulness, or education-intelligence. Age was, however, positively associated with preferences for confidence-assertiveness. Consistent with family formation goals, age was associated with an ideal partner's parenting intentions (high until approximately age 30, then decreasing afterward). Age range deemed acceptable (and in particular, the discrepancy between one's own age and the minimum ideal age of a partner) increased with age. This latter pattern also replicated in exploratory analyses based on subsamples of lesbian and bisexual women. In summary, age has a limited impact on partner preferences. Of the attributes investigated, only preference for confidence-assertiveness was linked with age. However, age range deemed acceptable and an ideal partner's parenting intention, a dimension mostly neglected in earlier research, substantially vary with age.

Is Sexual Racism Still Really Racism? Revisiting Callander et al. (2015) in the USA

As research on race and racism in the USA has suggested that it now takes a more subtle and neoliberal form, one of the areas in which race and racism are most explicit is in dating and sex. When finding dating and sexual partners, people tend to be explicit about their rejection of potential mates along racial lines while claiming that these preferences have no connection with racism. Callander et al.'s (2015) study was the first to provide the evidence that these expressions of sexual racism, or race-based rejections of partners in sexual contexts, were in fact related to cultural racism perpetuated in society at large. Despite all of this, the study has never been replicated. We aimed to partially replicate the study in the USA, using a sample of 616 gay, bisexual, and heterosexual men. Using the Quick Discrimination Index and online sexual racism surveys referenced in the original paper, we find a correlation of - 0.129, between the two measures. This suggests that respondents who demonstrate more openness and less racist beliefs in general are also less likely to be accepting of forms of online sexual racism, a finding that is consistent with prior research. Still, the correlation between these measures is not nearly as strong as that observed in Australia in the original paper (- 0.56), raising questions that require further exploration.

Human Leukocyte Antigen similarity decreases partners' and strangers' body odor attractiveness for women not using hormonal contraception

The Human Leukocyte Antigen (HLA) is a gene complex that encodes important elements of the human immune system. HLA profile is communicated via olfaction and interindividual diversity is assumed to be advantageous for mate choice. Additionally, HLA diversity appears to enhance satisfaction and sexual attraction in existing romantic partnerships. However, whether this effect is transmitted via body odors and whether it results in an attraction towards HLA-dissimilar individuals and/or an avoidance of HLA-similar ones remains unclear. In the present study, we genotyped couples and asked each participant to rate a body odor sample from their partner and from three strangers of the opposite sex who expressed a similar or dissimilar HLA-B and HLA-C genotype. We found no statistically significant preference for HLA similarity or dissimilarity in men. Among women, the observed effects differed depending on hormonal contraception status. Like men, women on hormonal contraception did not exhibit significant HLA-related preferences. However, for women not using hormonal contraceptives, odors from HLA-B and HLA-C similar donors were significantly less attractive than those from HLA-dissimilar donors, regardless of whether the samples were from a partner or a stranger. Our findings support the hypothesis that HLA similarity is perceived via body odors and that such similarity affects human attraction. This mechanism may serve an evolutionarily adaptive function in preventing prospective offspring from having decreased immunocompetence, or decreasing the chance of kin mating.

Domestic violence shapes Colombian women's partner choices

Abstract

Potential protection from violence has been suggested as an explanation for women’s preferences for more masculine partners. Previous studies, however, have not considered that violence may be multi-modal, and hence come from different sources. Therefore, we tested the effect of different fears of violence (i.e. vulnerability to public crime, likelihood of within-partnership violence) on masculinity preferences of women from Colombia, a country known for its high rates of violence. Eighty-three adult heterosexual women (mean age ± SD = 26.7 ± 6.01) answered a survey that included questions about health (e.g. frequency of illnesses during the last year and during childhood), access to media (e.g. time spent watching television, frequency of internet use), education (i.e. highest level achieved) and violence perceptions. Participants’ masculinity preferences for Salvadoran, European and Colombian male faces were recorded. Factor analysis revealed two different factors for the answers to questions related to violence. One factor loaded mostly on questions related to public violence and the second factor related to domestic violence. We found that women with higher scores on the domestic violence factor preferred significantly less masculine Colombian male faces. Even after controlling for participant age, education, access to media (TV and internet) and health-related factors, the domestic violence factor contributed significantly to explaining masculinity preferences. The results presented here suggest that women’s preferences for masculinity may be a strategy to avoid aggressive partners and that the source of violence matters in mate choice.

Significance statement

Women who perceive higher risks of domestic violence prefer less masculine looking partners. Using an experimental approach, we show that Colombian women who feel more in danger of violence within partnership prefer the faces of less masculine males. This was true even after controlling for women’s education level, health and access to media.

Preferences for Masculinity Across Faces, Bodies, and Personality Traits in Homosexual and Bisexual Chinese Men: Relationship to Sexual Self-Labels and Attitudes Toward Masculinity

This study examined preferences for masculinity across faces, bodies, and personality traits in 462 homosexual and bisexual men in China. The impact of sexual self-labels (tops, bottoms, and versatiles) and attitude toward male masculinity on preferences for masculinity were also examined. Participants were asked to select the seven most desirable personality traits for a romantic partner from a list of 32 traits of gender roles. A series of 10 masculinized and feminized dimorphic images of male faces and bodies were then presented to participants, who were required to identify their preferred image. The results indicated that participants preferred more masculine faces, bodies, and personality traits. Significant differences in preferences for masculinity were found between tops, bottoms, and versatiles, with both bottoms and versatiles preferring more masculine faces, bodies, and personality traits than did tops. In addition, preferences for masculinity across faces, bodies, and traits showed a significant positive correlation with each other for all sexual self-labels, indicating a consistent preference for masculinity. Attitude toward male masculinity was significantly correlated with facial, body, and trait preferences; individuals with more rigid attitudes toward male masculinity (low acceptance of femininity in males) preferred more masculine characters. These results indicate a consistent preference for masculinity between both physical features (faces and bodies) and personality traits (instrumentality) that may be affected by observer perception.
