Zhana Vrangalova is a human sexuality researcher with a PhD in Developmental Psychology from Cornell University. Currently she teaches in the Psychology Department at NYU. Her research focuses on sexual orientation, consensual non-monogamy, and the effects of casual sex on emotional wellbeing. She is the originator of The Casual Sex Project, a forum for real stories from real people detailing their experiences with hookups, one-night stands, friends with benefits, and the like. Her recently published study, Who Benefits from Casual Sex: The Moderating Role of Sociosexuality, is generating a great deal of discussion among not just sexologists, but the general public, primarily because the research finds that casual sex, for people who are emotionally and socially “into it,” may actually benefit emotional and psychological wellbeing. (Previous studies looking into the effects of casual sex on wellbeing have been largely inconclusive.) I recently had the opportunity to speak with Zhana about her groundbreaking work, and I wanted to share the transcript of our conversation here.
