NOTE: This episode contains some adult discussion which includes topics of sexual assault and abuse. Have you ever wondered about the secret and sometimes dark world of a human's "special" desires? Dr. Wendy asks Kinsey Institute's Dr. Justin Lehmiller if scientists have discovered an evolutionary basis for our fantasy worlds and fetishes. Oh, yeah, and a whole lot more! Lehmiller is a social psychologist and the author of "Tell Me What You Want: The Science of Sexual Desire and How It Can Help You Improve Your Sex Life." His writing can also be found at sexandpsychology.com Contact Dr. Wendy and Mating Matters at [email protected] or (323) 207-8277.
