Cindi Loftus started a thread on her site about strange fetishes. Balloons, pantyhose, things like that? But being the increasingly degenerate species that we are, I knew there had to be some stranger ones. Try
The Encyclopedia of Unusual Sex Practices. If you've got some fuck-ed up fetishes, chances are this author Brenda Love has given it a name. Here's a sample:
Agalmatophilia: Arousal from statues or mannequins.
Anaclitism: Arousal by reenactment of infant activities. This category is subdivided into coprophilia (arousal during toilet training), soiled diapers (mysophilia), and something called womb confinement.
Anthropophagy: Arousal gained by consuming human skin. "Autophagy" is a subset, arousal from eating your own skin.
Bastinado: Practice of beating or punishing the soles of one's feet.
Dendrophilia: Desire to copulate with trees. No word on sex with cactuses, though I'd call it "pain."
Formicophilia: Arousal from insects crawling on one's genetalia.
Entry # 230 -- "Marriage" LOL.
Ophidicism: Practice of inserting snakes into the vagina for arousal.
Sitophilia: Use of food for sxual arousal.
Urtication: Use of leaves with nettles (e.g. fern leaves) for arousal. Apparently it produces a reddened, sensitive feeling where they are struck/rubbed whatever. "Men who wear condoms have found that briefly applying nettles to the penis before putting on the condom can compensate for the sensation lost by the latex barrier."
