ITHACA, N.Y. (CBS Connecticut) – A new study finds that women are wary of others who sleep around.

According to Cornell University researchers, college-aged women judge their promiscuous female peers more negatively than they do chaste women, to the point where they view the former group as unsuitable for friendship.

Promiscuous females were defined by researchers as those who have had at least 20 sexual partners by their early twenties.

Even the participants who had a more liberal attitude towards casual sex or a high number of lovers still preferred having less sexually active women as friends.

Men showed similar leanings in regards to friendships with sexually experienced men, according to the study – though the hesitation in that regard was said to be caused by seeing promiscuous men as a threat.

Lead author Zhana Vrangalova, a graduate student in the field of human development in the College of Human Ecology, suggested that the findings show women still face a double standard that shames “slutty” women and celebrates “studly” men.

“Sexually permissive women are ostracized for being ‘easy,’ whereas men with a high number of sexual partners are viewed with a sense of accomplishment,” Vrangalova told Medical Express. “What surprised us in this study is how unaccepting [sic] promiscuous women were of other promiscuous women when it came to friendships – these are the very people one would think they could turn to for support.”

The 751 college students who participated in the study provided information about both their sexual experience and their views on casual sex. The number of sexual partners people in the focus group had ranged from 2 to 20.

The study was published in the Journal of Social and Personal Relationships.
