As Simpson and Bruckheimer's success grew, so did Simpson's reputation as a "party animal". He said that "next to eating and having sex, making movies is the best thing in the world". Simpson's debaucherous lifestyle was well-known in Hollywood and has been documented in a number of sources. He was a fixture on the "Hollywood cocaine-party" circuit throughout the 1970s and '80s, and in his later years became known for throwing lavish all-night parties at his mansion. An entire chapter of the book "You'll Never Make Love in This Town Again" (which describes four prostitutes' stories about their sexual encounters with Hollywood celebrities) discusses his frequent sex parties and preference for S & M. He also gave himself testosterone shots to boost his sex drive. According to the call girl Alexandra Datig, Simpson auditioned struggling actresses for his movies, convinced them to have sex with him, and secretly filmed their sex acts.
