Imagine a sex party where one of the guests is HIV positive and no one knows who it is -- and no one is allowed to use protection. In this episode co-host Noah Michelson speaks with psychotherapist, sexologist and sex therapist Dr. Michael Aaron to find out more about these alleged sex roulette parties, how the story might have originated and the psychology behind people who get a thrill from sexual practices that many others might consider unorthodox or even dangerous. Elsewhere in the episode, Noah & Carina chat about some of the biggest sex headlines of the week -- including why you may never want to have sex in front your TV ever again -- and answer a few listener questions like "Is it OK to fantasize about rape?"
