Maggie Mayhem is an HIV Tester/Counselor, sex blogger and activist, BDSM player, and San Francisco Sex Information Hotline volunteer. She's also one of Kink.com's newest models. Before Lochai tied her up for her very first shoot, a new episode of Casting Couch, Behind Kink sat down with her for an introspective face-to-face about how what she does is so integral to who she is.
