In his book, Perv: The Sexual Deviant in All of Us, psychologist and writer Jesse Bering challenges the social and psychological biases when it comes to sexuality. Growing up gay in Washington, DC during the time of the AIDS crisis, society saw Bering as a sexual deviant.

Bering was recently discussed his book on CBC Radio's Q, with guest interviewer Piya Chattopadhyay. To listen to the full interview, click here.
