You might think that an asylum is a controlled, sex-less environment, but as we see in the story of imprisoned 18- and 19th-Century writer and pervert Marquis de Sade (Geoffrey Rush), he is able to produce and smuggle out kinky tales using quill and ink, wine, blood, feces, and narration through a chain of crazies. And for S&M fans, treatments including water torture and an iron dummy are just what the doctor ordered!
