"Men's brains are wired for attraction to sexually dimorphic faces" "

Sexual dimorphism isn't as dirty as you think it sounds. It refers to the differences the sexes of the same species. For example, male peacocks are much more colorful than their female counterparts.

In humans, sexually dimorphic male faces have broad jaws and forehead and more pronounced brow ridge. Female faces have a tapered chin, larger lips and narrower forehead.

In a Harvard study, participants were asked to rate the attractiveness of faces that were altered to be more masculine or feminine. This study also included lesbian and gay participants.

The results showed:

• Gay men prefer highly masculine males faces rather than feminine males faces
• Type of male faces found attractive by gay men did not agree with the types of male faces straight women thought were attractive
• Gay men and straight men also did not agree on which male faces were attractive
• Straight women like more masculine male faces than lesbians
• Lesbian preferred more slightly masculine female faces than straight men and women

Previous research has shown women prefer more masculine males faces during ovulation, suggesting an evolutionary connection to human sexual dimorphism. Also, women's attractions are much more complicated then men as it depends on contraception use, self-perceptions, ovulation and sex drive.

The conclusion from this study is that men, regardless of orientation, prefer sexually dimorphic faces synoynmous with the gender they attracted to--gay men like masculine male faces and straight men like feminine female faces.
