Twinks, Fairies, and Queens: A Historical Inquiry into Effeminate Gay Bottom Identity

Effeminate gay bottoms, or gender nonconforming men who are anally receptive and/or give oral sex to other men who are also "gender nonconforming," are persistently marginalized in gay and LGBTQ+ communities in Britain and the US. For some LGBTQ+ commentators, "twink" has become relexified to mean a young-looking, slim, hairless effeminate bottom, whereas originally the term primarily denoted a body type and age bracket among gay men. This article explores how the twink has come to bear connotations of effeminacy and bottom subjectivity, highlighting the steady erosion of other available cultural terms to denote a bottom whose gender expression does not conform to dominant cultural masculine stereotypes. It offers an analysis of two key historical effeminate bottom identities in Britain and the US, the "fairy" and "queen," and argues that the twink not only now carries connotations originally attached to these historical identities, but that it merges their gendered and sexual connotations with new characteristics concerning age and body type that may cause considerable anxiety among contemporary gay men due to their unsustainable "shelf life."

Does the Fraternal Birth Order Effect Influence Handedness?

The fraternal birth order effect (FBOE) is the phenomenon whereby the probability that a man has a same-sex sexual orientation in adulthood increases with each biological older brother. Several studies have found evidence that the FBOE is limited to right-handed men, and left-handed men do not show an FBOE. Recent debates about the appropriate methods for quantifying the FBOE center on distinguishing the FBOE from other effects, such as the female fecundity effect (FFE), whereby mothers more prone to bearing gay sons are also more fecund. The FBOE and FFE are confounded in that a real FFE will result in data consistent with the FBOE under some analyses. Here, we applied some recent proposed analytic methods for the FBOE to the property of handedness. A straightforward application of Khovanova's technique to the binary trait of handedness yielded support for a fraternal birth order effect consistent with the maternal immune hypothesis, in that the ratios of handedness differed between men with one older brother only, and men with one younger brother only, while no such effect was seen in women. This effect was not seen, however, when the confounding effects of parental age were controlled for. Models including factors to simultaneously test multiple posited effects find significant female fecundity effects, as well as paternal age and birth order effects on handedness in men, but no FBOE. The effects seen in women were different, with no fecundity or parental age effects, but birth order and sex of older siblings had effects. We conclude, based on this evidence, that many of the factors thought to contribute to sexual orientation in men may also have an influence on handedness, and further note that parental age is a potential confound which may be overlooked by some analyses of the FBOE.

Carving the Biodevelopment of Same-Sex Sexual Orientation at Its Joints

Sexual orientation is a core aspect of human experience and understanding its development is fundamental to psychology as a scientific discipline. Biological perspectives have played an important role in uncovering the processes that contribute to sexual orientation development. Research in this field has relied on a variety of populations, including community, clinical, and cross-cultural samples, and has commonly focused on female gynephilia (i.e., female sexual attraction to adult females) and male androphilia (i.e., male sexual attraction to adult males). Genetic, hormonal, and immunological processes all appear to influence sexual orientation. Consistent with biological perspectives, there are sexual orientation differences in brain development and evidence indicates that similar biological influences apply across cultures. An outstanding question in the field is whether the hypothesized biological influences are all part of the same process or represent different developmental pathways leading to same-sex sexual orientation. Some studies indicate that same-sex sexually oriented people can be divided into subgroups who likely experienced different biological influences. Consideration of gender expression in addition to sexual orientation might help delineate such subgroups. Thus, future research on the possible existence of such subgroups could prove to be valuable for uncovering the biological development of sexual orientation. Recommendations for such future research are discussed.

To What Extent are Prenatal Androgens Involved in the Development of Male Homosexuality in Humans?

Endocrine variations, including possibly reduced exposure to androgens, may contribute to the development of male homosexuality, with animal models demonstrating same-sex mate preference with altered exposure during prenatal or early postnatal development. As similar studies in humans are impossible, indirect physical and cognitive measures of androgen exposure are used. Some studies suggest that physical measures affected by prenatal androgens, including the index-to-ring finger ratio, growth indices, and facial structure, are more "feminine" in gay men. Gay men also exhibit significant childhood gender non-conformity and a "feminized" anatomical and functional brain pattern in sexual arousal, as well as domains such as language, visuospatial skills and hemispheric relationships. However, many of these results are equivocal and may be confounded by other factors. Research has also been hampered by inconsistencies in the reporting of sexual orientation and the potentially unrepresentative populations of gay men studied, while additional complexities pertaining to gender conformity and sexual role may also influence results.

Top, Bottom, and Versatile Orientations among Adolescent Sexual Minority Men

Sexual role preference or self-label (i.e., top, versatile, or bottom) has been well studied in samples of sexual minority men (SMM) but lacks research among adolescent sexual minority men (ASMM). In response, data were collected from 302 ASMM (15-18 years old), measuring sexual self-label, relationship and sexual experience, sexually explicit media use, use of geosocial networking applications, penis size satisfaction, and gender atypicality. Results showed there was no significant difference in the distribution of sexual position self-identity in ASMM when compared with data from published, adult samples. A model that associated sexual socialization factors with adopting any self-label was significant, with greater number of partners, previous geosocial networking app use, and more relationship experience being positive predictors of having a label. Additionally, a model that tested the convergent validity between self-label and enacted sexual behaviors was significant. Both receptive and insertive sex enactments were highly correlated with corresponding labels. Lastly, gender atypicality and penis size satisfaction were significant predictors of sexual position self-identity. Data from our study supports sexual self-labeling occurring before adulthood, during adolescence for SMM. Furthermore, it shows that socialization factors (e.g., partner frequency, using apps) are important in the development of sexual position self-identity in this population.

Recalled Childhood Separation Anxiety Differs by Anal Sex Role among Gay Men

Male androphilia (i.e., male sexual attraction to adult males) is considered an evolutionary paradox because it is partially influenced by genes and associated with decreased reproduction. Traits associated with attachment to genetic relatives (i.e., kin) could prompt increased kin-directed altruism, thereby offsetting decreased reproduction by helping kin reproduce. These traits include childhood separation anxiety and adulthood neuroticism, which have been associated with feminine gender expression. In prior research, gay men with a receptive (Bottom or Versatile) anal sex role (ASR) reported greater childhood gender nonconformity (GNC) than those with an insertive (Top) ASR. We examined whether ASR groups also differed on recalled childhood separation anxiety and adulthood neuroticism. The Separation Anxiety Scale-Revised and Big-Five Personality Inventory - short form were completed by 350 gay and 146 heterosexual men. For neuroticism, ASR preference groups differed from heterosexual men but not from one another. Gay men who preferred a Bottom or Versatile ASR reported higher recalled childhood separation anxiety than Tops and heterosexual men. Recalled childhood GNC mediated ASR group differences with heterosexual men on childhood separation anxiety. These results indicate that subgroups of gay men delineated by ASR differ on an evolutionarily relevant developmental trait, childhood separation anxiety.

Effeminate Gay Bottoms in the West: Narratives of Pussyboys and Boiwives on Tumblr

Recent discussions of gay male bottom identity have been cautious about positioning bottoms in relation to a gendered identity, and thereby colluding with stereotypes about gay bottoms being effeminate and effeminate gays being bottoms. In wider LGBTQ media in Europe and North America there is an effort to destigmatize effeminate gay men in a dating culture that privileges "masc4masc." While this is welcome, it obscures the existence of effeminate gay bottom fantasies that are gender stratified and which insist on a connection between sex role preference, sex object choice, and gender presentation. This paper analyses sexual fantasy narratives on the social media platform, Tumblr, and interrogates a deep structure of gender-stratified male androphilia that finds thematic similarities in non-Western settings, where "egalitarian" or Western "gay" expressions of male same-sex unions compete with traditional "heterogender" forms. It concludes by reaffirming the need to consider gender positionality among gay bottoms' narratives in Western contexts, and for further research on Western gay men to recognize the heterogeneity of gay identities and experiences.

Intersectional Effects of Sexual Orientation Concealment, Internalized Homophobia, and Gender Expression on Sexual Identity and HIV Risk Among Sexual Minority Men of Color: A Path Analysis

ABSTRACT

In the United States, 13 million people identify as sexual and gender minorities. The purposes of this article were to (a) examine the associations among sexual orientation concealment and internalized homophobia with HIV knowledge, health literacy, and transactional sex through sexual identity; and (b) assess whether gender expression moderates those relationships in sexual minority men of color. A multigroup mediation path model examined the association between sexual orientation concealment and internalized homophobia on HIV knowledge, health literacy, and transactional sex through sexual identity by gender expression. Results suggest that, among those with a masculine gender expression, as sexual concealment increased, health literacy decreased. The association between sexual orientation concealment and transactional sex varied by participant's gender expression as did the association between internalized homophobia and HIV knowledge. Multiple intersecting identities, when faced with anticipated discrimination and homophobia, can negatively affect health outcomes and increase HIV risk in sexual minority men of color.

Handedness and Birth Order Among Heterosexual Men, Gay Men, and Sao Praphet Song in Northern Thailand

Previous research has examined handedness and birth order to inform sexual orientation and gender identity/role expression development; however, sexual orientation and gender identity/role expression have rarely been disentangled to provide a more nuanced perspective. In Thailand, we investigated sexual orientation and gender identity simultaneously via comparison of 282 heterosexual men, 201 gay men, and 178 sao praphet song-i.e., androphilic, markedly feminine males recognized as a "third" gender. Handedness was examined as: extremely left-handed, moderately left-handed, ambidextrous, moderately right-handed, or extremely right-handed. Birth order was examined as numbers of older and younger brothers and sisters, by using Berglin's, fraternal, and sororal indices, and by examining the older brother odds ratio and sibling sex ratio. Compared with heterosexual men, gay men and sao praphet song were more likely to be extremely right-handed. Sao praphet song were also more likely to be extremely left-handed than heterosexual and gay men. Heterosexual men and sao praphet song had later sororal birth order compared with the expected Thai population value, suggesting stopping rules influenced when probands' mothers ceased having children. These findings provide new insights and replicate previous findings in a non-Western sample. Regarding handedness, in males, mechanisms related to extreme right-handedness likely influence the development of androphilia, whereas mechanisms related to both extreme right- and extreme left-handedness likely explain the combination of androphilia and feminine gender identity/role expression. Regarding birth order, similar to the conclusions of some prior research, stopping rules pose a challenge for testing the fraternal birth order effect.

Evidence for distinct biodevelopmental influences on male sexual orientation

Several biological mechanisms have been proposed to influence male sexual orientation, but the extent to which these mechanisms cooccur is unclear. Putative markers of biological processes are often used to evaluate the biological basis of male sexual orientation, including fraternal birth order, handedness, and familiality of same-sex sexual orientation; these biomarkers are proxies for immunological, endocrine, and genetic mechanisms. Here, we used latent profile analysis (LPA) to assess whether these biomarkers cluster within the same individuals or are present in different subgroups of nonheterosexual men. LPA defined four profiles of men based on these biomarkers: 1) A subgroup who did not have these biomarkers, 2) fraternal birth order, 3) handedness, and 4) familiality. While the majority of both heterosexual and nonheterosexual men were grouped in the profile that did not have any biomarker, the three profiles associated with a biomarker were composed primarily of nonheterosexual men. We then evaluated whether these subgroups differed on measures of gender nonconformity and personality that reliably show male sexual orientation differences. The subgroup without biomarkers was the most gender-conforming whereas the fraternal birth order subgroup was the most female-typical and agreeable, compared with the other profiles. Together, these findings suggest there are multiple distinct biodevelopmental pathways influencing same-sex sexual orientation in men.

Individual differences in the biological basis of androphilia in mice and men

For nearly 60 years since the seminal paper from W.C Young and colleagues (Phoenix et al., 1959), the principles of sexual differentiation of the brain and behavior have maintained that female-typical sexual behaviors (e.g., lordosis) and sexual preferences (e.g., attraction to males) are the result of low androgen levels during development, whereas higher androgen levels promote male-typical sexual behaviors (e.g., mounting and thrusting) and preferences (e.g., attraction to females). However, recent reports suggest that the relationship between androgens and male-typical behaviors is not always linear - when androgen signaling is increased in male rodents, via exogenous androgen exposure or androgen receptor overexpression, males continue to exhibit male-typical sexual behaviors, but their sexual preferences are altered such that their interest in same-sex partners is increased. Analogous to this rodent literature, recent findings indicate that high level androgen exposure may contribute to the sexual orientation of a subset of gay men who prefer insertive anal sex and report more male-typical gender traits, whereas gay men who prefer receptive anal sex, and who on average report more gender nonconformity, present with biomarkers suggestive of low androgen exposure. Together, the evidence indicates that for both mice and men there is an inverted-U curvilinear relationship between androgens and sexual preferences, such that low and high androgen exposure increases androphilic sexual attraction, whereas relative mid-range androgen exposure leads to gynephilic attraction. Future directions for studying how individual differences in biological development mediate sexual behavior and sexual preferences in both mice and humans are discussed.
