This episode was originally released on January 13, 2018. Orgies. Sex in public. Incest. These are the things that some of us think about in the dark. Taboo fantasies can be exciting, but they can also be the source of our deepest shame. In this two-part series on sexual fantasies, the Sugars read letters from people who want to turn off the thoughts that turn them on. Dr. Ian Kerner, a psychotherapist and sexuality counselor, helps the Sugars answer a letter from a woman who calls herself “Fed Up With Fantasy.” She writes, “Ever since I started being a sexual being I’ve had terrible fantasies. Incest of every kind. Teachers having sex with their underage students. Gangbangs in public bathrooms. I cannot get turned on without thinking of these story lines. Did something bad happen to me that I have repressed so much I don’t even have a hint of it?” she asks. “And how do I make it stop?” Dr. Kerner and the Sugars explore where dark fantasies come from and offer “Fed Up With Fantasy” ways she can share them with her boyfriend. Dr. Kerner specializes in sex therapy and couples therapy. He’s also The New York Times best-selling author of “She Comes First: The Thinking Man’s Guide to Pleasuring a Woman.”
