Biography

Lehmiller is from Canton, Ohio. He attended college at Gannon University, earning a B.A. in psychology in 2001. In 2003, he graduated from Villanova University with a M.S. in experimental psychology. In 2008, he received his doctorate in social psychology from Purdue University. Lehmiller began his academic career as an assistant professor in the Department of Psychology at Colorado State University (2008–2011). Following that, he served as a College Fellow in the Department of Psychology at Harvard University (2011–2014) and as the director of the Social Psychology Graduate Program at Ball State University (2015–2018).

Lehmiller's book Tell Me What You Want was published by Da Capo Press in 2018. The book is based on the largest-ever survey of sexual fantasies in the United States. Lehmiller's survey of 4,175 Americans offers insight into what Americans are fantasizing about, where people's sexual fantasies come from and what they say about an individual, and how to communicate about fantasies with a partner. In January 2020, Lehmiller appeared on an episode of the Netflix series Sex, Explained, in which he discussed some of the main findings from his book.

Lehmiller collaborated with advice columnist, Dan Savage, to study gay men's cuckolding fantasies, publishing the findings in the Archives of Sexual Behavior, a peer-reviewed journal for research on sexuality. He has also published on sexual fantasies, consensual non-monogamy, marginalized relationships, and friends with benefits.

Lehmiller is a consulting editor at The Journal of Sex Research and an elected member of the International Academy of Sex Research.

Lehmiller has appeared on several television programs to discuss his research and the science of sex, including Dr. Phil, Sex Before the Internet, and National Geographic's Taboo. He maintains the Sex and Psychology blog and podcast.
