The results showed that although straight women expressed more subjective arousal to the film with one man and one woman and lesbian women expressed more subjective arousal to the film involving two women, both heterosexual and lesbian women were equally physiologically aroused by all three films (Chivers et al., 2004). The women then reported their feelings of sexual arousal to the films, and the researchers used objective measures of physiological and genital arousal as a comparison. Researchers presented women with three sexual films, one showing two women, one showing a man and a women, and the last showing two men.

These researchers stress that women are not attracted to their relatives per se (in fact, women even avoid their fathers when fertile see Lieberman et al., 2011) rather, these preferences may indicate that women are looking for a man who resembles their family members, because genes that are somewhat similar to their own, but still different enough, may be optimal for reproductive success (Saxton et al., 2017). Similarly, in another study, women were most strongly sexually attracted to photographs of men which had been morphed with photographs of their fathers (Fraley and Marks, 2010). Women's brothers were ranked as most similar-looking to women's romantic partners (Saxton et al., 2017). For example, in one project, respondents compared facial photographs of women's romantic partners with photographs of unrelated men and photographs of the women's brothers.

Interestingly, women also may be most interested in dating men of another ethnic background when fertile (Salvatore et al., 2017).ДЄ variety of disturbing research shows that heterosexual women are unconsciously attracted to men who resemble their fathers, their brothers, and even themselves (Fraley and Marks, 2010 Little et al., 2003 Saxton et al., 2017). Even after choosing a mate, when estrogen levels are high, women are more interested in sex with men other than their partners, while when progesterone levels are high, women are more interested in sex with their primary partners (Grebe et al., 2016). Fertile women also prefer the scent of men who are symmetrical, and thus likely to possess good genes (see Thornhill and Gangestad, 1999). However, during the non-fertile portion of women's cycles, they prefer men with more feminine facial features. When women are in the most fertile portion of their cycles, and their likelihood of conception is the highest, women are more attracted to men with very masculine-looking faces (Johnston et al., 2001 Little et al., 2008), a potential indicator of genetic quality. Women are usually unaware of whether they are in the fertile or non-fertile portion of their menstrual cycle, yet women's attraction varies greatly across the cycle. In this research project, few of the couples were married, but women also reported having more affairs when their immune genes were more similar to their boyfriends' genes. (2006) found that women reported decreased sexual arousal and an increased likelihood of rejecting men's sexual advances when they shared more immune genes with their partners. But even after we have chosen a mate, these genes may continue to influence our attraction to our partners. There is evidence that heterosexual women are likely to marry men with immune genes which are different from their own (Ober et al., 1997, as cited by Garver-Apgar et al., 2006). Evolutionarily speaking, it is useful to mate with a partner who possesses immune genes unlike our own in order to enhance the immunity of future offspring. Major histocompatibility complex (MHC) genes in our immune system unconsciously influence our sexual desires. We do not often think about the possibility that our genetic background impacts our attraction to others however, our genes can have a significant impact on our sexual attraction to potential partners.
