As a sex therapist in private practice, I’ve treated many clients with sleep fetishes of various kinds. The clinical term is “somnophilia,” a paraphilia in which sexual arousal arises from fondling or having sex with someone who is asleep or unconscious. A more romantic name for it is the “Sleeping Beauty” syndrome. The fairy tale fantasy of an exquisitely beautiful, utterly helpless princess in a deep, hypnotic, erotic sleep that only awakens, with the climactic kiss of a charming prince, has captured imaginations and titillated libidos for centuries of civilized human history. If Prince Charming had given Beauty a roofie and then done his kissing and maybe a little fondling, he’d be a nonconsensual sleep fetishist, a.k.a., a sleep rapist. Not so charming any more.
The other side of the sleep fetish, getting sexually aroused by having sex with slumbering lovers, is far more dangerous to others than to the fetishist, especially when it involves putting “lovers” to sleep without their consent and then using their knocked out, very vulnerable, rag-doll body to satisfy desires for absolute power, selfish sensation and an intoxicating feeling of total control. If the allegations are true, this appears to describe the sexual appetites and behaviors of Bill Cosby.There's an Australian sex movie about this, by the way, called Sleeping Beauty, available on Netflix.
