This spring, the Kinsey Institute welcomes Dr. Justin Lehmiller as a contributing writer to the Kinsey Institute website. We will be featuring new articles  by Dr. Lehmiller on a variety of sex research and sex education topics on the Kinsey Institute website and across our social media platforms.

Dr. Lehmiller is an award winning educator and a prolific researcher and scholar. He has published articles in some of the leading journals on sex and relationships, written two textbooks, and produces the popular blog, Sex & Psychology. Dr. Lehmiller's research topics include casual sex, sexual fantasy, sexual health, and friends with benefits. He is currently the Director of the Social Psychology Graduate Program and an Assistant Professor of Social Psychology at Ball State University.

Dr. Lehmiller is also currently conducting two studies to shed light on both the prevalence and psychological underpinnings of troilism fantasies. The first study investigates how troilism fantasies are related to sex, attachment style, and personality in a diverse internet sample. The second study examines troilism fantasies among gay and bisexual men and considers how they are similar/different relative to those of heterosexual men. The results from both studies suggest that troilism is anything but an unusual sexual interest—especially among men—and offer insight into the psychological origins of this desire.
