The frequency of homoerotic behavior among individuals who do not identify as having an exclusively homosexual sexual orientation suggests that such behavior potentially has adaptive value. Here, we define homoerotic behavior as intimate erotic contact between members of the same sex and affiliation as the motivation to make and maintain social bonds. Among both male and female nonhuman primates, affiliation is one of the main drivers of homoerotic behavior. Correspondingly, in humans, both… 
Facilitating and Inhibiting Factors for Self-Reports of Same-Gender Attraction in Cisgender Heterosexual-Identifying Women and Men
TLDR
Both anti-gay attitudes and felt-pressure to conform to gender stereotypes appear to be reliably associated with same-gender attraction.
Prosociality and a Sociosexual Hypothesis for the Evolution of Same-Sex Attraction in Humans
TLDR
It is argued that for humans the social functions and benefits of sex apply to same-sex sexual behavior as well as heterosexual behavior, and a degree of SSSA, was selected for in recent human evolution for its non-conceptive social benefits.
A Life History Approach to the Female Sexual Orientation Spectrum: Evolution, Development, Causal Mechanisms, and Health
TLDR
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.
Born Both Ways: The Alloparenting Hypothesis for Sexual Fluidity in Women

TLDR
Thealloparenting hypothesis is proposed, which posits that sexual fluidity in women is a contingent adaptation that increased ancestral women's ability to form pair bonds with female alloparents who helped them rear children to reproductive age.

TLDR
It is argued that intense sexual pleasure, especially orgasm, can be understood as a primary reinforcer shaped by evolution to reinforce behavior that facilitates reproductive success (i.e. conception through copulation).

Two studies were conducted to better understand individual difference factors that influence women’s mating-relevant perceptions of other women. In Study 1, biases about revealing dress were examined

The alliance theory of homosexual behavior and the perception of social status and reproductive opportunities.
TLDR
The alliance theory of homosexual behavior may have heuristic value for the evolutionary study of homosexuals behavior and its perception.

TLDR
Exaptation is suggested as a theoretical framework for interpreting homosexual behavior and it is concluded that future consideration of sexual selection among primates should address homosexual components of this process.
Is homophobia associated with homosexual arousal?
TLDR
The authors investigated the role of homosexual arousal in exclusively heterosexual men who admitted negative affect toward homosexual individuals and found that only the homophobic men showed an increase in penile erection to male homosexual stimuli.

We argue that explanations of homosexual function in evolution have often been based on homosexual organization in Western societies and on modern homosexual subcultures. We suggest that if
The Evolution of Human Homosexual Behavior1
TLDR
Three adaptationist hypotheses are reviewed here and compared with the anthropological literature and support is strongest, however, for the hypothesis that homosexual behavior comes from individual selection for reciprocal altruism.
The Evolution of Homoerotic Behavior in Humans
TLDR
It is posited that humans evolved a disposition for homoerotic behavior because it increased same-sex affiliation among peripheralized hominids and indirectly influenced rates of survival and reproductive success.
The Evolution of Male-Male Sexual Behavior in Humans
TLDR
It is argued that the evolutionary origin of male-male sexual behavior is based on the same dominance-submission mechanisms that gave rise to male-female sexual behavior and exclusive same-sex attraction in human males is due to an interaction between genetic, cultural, developmental and psychological factors.
