About Sex and Psychology and Dr. Lehmiller

Sex and Psychology was created in order to share the science of sex, love, and relationships in a way that is both engaging and accessible. It is departure from most of the other sexual advice websites out there, which are run by self-proclaimed experts who base their information largely upon their own personal experiences and beliefs. This is not a personal, opinion-based blog; rather, each article on here is rooted in science and actually cites the original research sources. The goal is for readers to learn responsible information about sex and relationships and to correct the numerous myths and misconceptions that actively harm our sexual health and well-being.  


This website is run by Dr. Justin J. Lehmiller, who received his Ph.D. in Social Psychology from Purdue University. He is currently the Director of the Social Psychology Graduate Program at Ball State University and a Research Fellow at The Kinsey Institute. Dr. Lehmiller is an award winning educator, having been honored three times with the Certificate of Teaching Excellence from Harvard University.
