Indie Sex is a series of documentaries broadcast on America's Independent Film Channel last year. Each episode deals with a different theme: Censored, Taboos, Teens, and Extremes. Each show features critics and directors discussing the history of (almost exclusively heterosexual) sex in cinema. Most of the film clips (with a few exceptions) are very tame, though the DVD includes more graphic sequences.
The first episode, Censored, gives a detailed history of American film censorship (and is less polemical than This Film Is Not Yet Rated). There is quite a lot of overlap, though, with the same points being made, and the same films being discussed, in several episodes. Among the directors interviewed are John Waters (discussing A Dirty Shame), Fenton Bailey (discussing Inside Deep Throat), Catherine Breillat (discussing Anatomy Of Hell), and John Cameron Mitchell (discussing Shortbus).
