If you're looking for really strange fetish try this one:
My patient was sneaking into the women's restrooms when no one was around. He'd rummage through the garbage and get out dirty diapers, and used feminine hygenie products. He would then eat the feces, and put the tampons and pads in his mouth. He told me "I turns me on...sexually"
Fortunatly he realized that this was a problem, and wanted to stop, mostly because he didn't want "Hepatitis or something".
Disorder increases with time because we measure time in the direction in which disorder increases.
