The "Furry" Phenomenon: Characterizing Sexual Orientation, Sexual Motivation, and Erotic Target Identity Inversions in Male Furries

Abstract

Furries are individuals who are especially interested in anthropomorphic or cartoon animals (e.g., Bugs Bunny). They often strongly identify with anthropomorphic animals and create fursonas, identities of themselves as those anthropomorphic animals. Some practice fursuiting, or wearing costumes that resemble anthropomorphic animals. Furries have been portrayed as sexually motivated in the media and popular culture, although little empirical research has addressed this issue. If some furries are sexually motivated, they may be motivated by an erotic target identity inversion (ETII): sexual arousal by the fantasy of being the same kinds of individuals to whom they are sexually attracted. Furries with ETIIs would experience both sexual attraction to anthropomorphic animals and sexual arousal by fantasizing about being anthropomorphic animals, because they often change their appearance and behavior to become more like anthropomorphic animals. We surveyed 334 male furries recruited from the Internet about their sexual orientation, sexual motivation, and sexual interests. A large majority of our sample reported non-heterosexual identities (84%) and some degree of sexual motivation for being furries (99%). Male furries also tended to report a pattern of sexual interests consistent with an ETII involving anthropomorphic animals. Both sexual attraction to anthropomorphic animals and sexual arousal by fantasizing about being anthropomorphic animals were nearly universal. Furthermore, male furries tended to be sexually aroused by fantasizing about being the same kinds of anthropomorphic animals to whom they were sexually attracted, with respect to gender and species. This sexual motivation and these unusual sexual interests do not justify discrimination or stigmatization.



A Life History Approach to the Female Sexual Orientation Spectrum: Evolution, Development, Causal Mechanisms, and Health

Abstract

Women's capacity for sexual fluidity is at least as interesting a phenomenon from the point of view of evolutionary biology and behavioral endocrinology as exclusively homosexual orientation. Evolutionary hypotheses for female nonheterosexuality have failed to fully account for the existence of these different categories of nonheterosexual women, while also overlooking broader data on the causal mechanisms, physiology, ontogeny, and phylogeny of female nonheterosexuality. We review the evolutionary-developmental origins of various phenotypes in the female sexual orientation spectrum using the synergistic approach of Tinbergen's four questions. We also present femme-specific and butch-specific hypotheses at proximate and ultimate levels of analysis. This review article indicates that various nonheterosexual female phenotypes emerge from and contribute to hormonally mediated fast life history strategies. Life history theory provides a biobehavioral explanatory framework for nonheterosexual women's masculinized body morphology, psychological dispositions, and their elevated likelihood of experiencing violence, substance use, obesity, teenage pregnancy, and lower general health. This pattern of life outcomes can create a feedback loop of environmental unpredictability and harshness which destabilizes intrauterine hormonal conditions in mothers, leading to a greater likelihood of fast life history strategies, global health problems, and nonheterosexual preferences in female offspring. We further explore the potential of female nonheterosexuality to function as an alloparental buffer that enables masculinizing alleles to execute their characteristic fast life history strategies as they appear in the female and the male phenotype. Synthesizing life history theory with the female sexual orientation spectrum enriches existing scientific knowledge on the evolutionary-developmental mechanisms of human sex differences.



Nasality in Homosexual Men: A Comparison with Heterosexual Men and Women

Abstract

Several studies reported that pitch and articulation may vary according to a person's sexual orientation. The purpose of this study was to investigate whether homosexual males also demonstrate differences in nasal resonance compared to heterosexual males. Speech samples of 30 self-identified homosexual males, 35 heterosexual males, and 34 heterosexual females were compared both instrumentally and perceptually. Nasalance scores were calculated for the sounds /a/, /i/, /u/, and /m/ and for an oronasal, oral, and nasal text. In addition, the Nasality Severity Index was determined. Spontaneous speech samples were used for a perceptual evaluation of nasal resonance. Neither the nasalance scores nor the Nasality Severity Index were significantly different between the homosexual and heterosexual males. Heterosexual females, on the other hand, showed significantly higher nasalance values for the oronasal and oral text and a significantly lower Nasality Severity Index than both the homosexual and the heterosexual males. The perceptual judgment revealed no significant differences between the three groups. The results of this study suggest that, in contrast to pitch and articulation, nasality does not tend to vary with sexual orientation.



Gender Dysphoria and Anorexia Nervosa Symptoms in Two Adolescents

Abstract

The co-occurrence of gender dysphoria and anorexia nervosa has been described in the scientific literature. This paper presents two adolescents with gender dysphoria and pathological eating behaviors and questions with longitudinal observations the clinical meaning of anorexia nervosa symptoms (e.g., restricting eating behaviors and fear of gaining weight) in adolescents with gender dysphoria. Both received psychological evaluations at different times: at first admission to the gender dysphoria clinic (T0) and 6 months after starting treatment with gonadotropin-releasing analogues (GnRHa; T1). In both cases, treatment with GnRHa not only improved psychological functioning, but also resolved pathological eating behaviors. In fact, both adolescents reported quick restoring of healthy food habits with restricting eating behaviors as well as intensive exercise no longer needed after treatment with GnRHa. Therefore, pathological eating behaviors (e.g., food avoidance and weight loss) could be assessed as a dysfunctional coping strategy adopted to gain control over a body developing in an unwanted direction and to block irreversible physical pubertal changes. This psychopathological conceptualization of pathological eating behaviors in adolescents with gender dysphoria stresses the importance of providing, in selected cases, early medical intervention such as pubertal suppression with GnRHa. Mental health professionals should therefore perform a specific and detailed assessment on gender identity within the evaluation of apparent eating disorders in adolescents. Restrictive eating behaviors as well as the intense fear of gaining weight or of becoming fat may, in fact, be considered secondary to a gender dysphoria diagnosis instead of anorexia nervosa symptoms.
