Chris chats with sex researchers Dr. Justin Lehmiller and Roni Wiener about sexual fantasies, thinking oneself to orgasm, the importance of sex research, and much more. Justin also speaks at length about his book, Tell Me What You Want: The Science of Sexual Desire and How It Can Help You Improve Your Sex Life, which is based on the responses 4,175 American adults gave to a 369-question survey about sexual fantasies. Check out his excellent blog sexandpsychology.com for more of Justin's musings on sex and science. You should also consider filling out Roni's diverse orgasm survey.
