WASHINGTON (CBS DC) – Women who hang out with more male friends and co-workers have more frequent sex with their boyfriends than women who have fewer male influences in their life.
The study — published in the Journal of Comparative Psychology — finds that men often perceive their female partner’s abundance of male friends to be a form of “sperm competition psychology,” in which the men have more sex with their girlfriends due to the potential of “sex rivals.”
The Oakland University study of 393 men in committed, sexual, heterosexual relationships found that human males – just as in nonhuman males – have more sex with their partner when they perceive that their female partner has an excess of male friends posing a “sperm competition risk.” This was made more evident when men perceived that their female partner was considered sexually attractive to the male “sex rivals” in her social circles.
