Might as well contribute to the list:

- Amputees / amputations, preferably complete removal of both arms. Quadruple amputations are hot too, but as a foot-use fetishist I like the idea of an armless girl doing everything with her feet.

- Feet, to a limited degree. Unlike what appears to be the majority of foot fetishists, I don't like dirty feet, sweaty or smelly feet, wrinkles, or fat feet - I prefer them clean, slender, and oddly enough with long dextrous toes, especially if they get used as substitute hands.

- Eye guro. This may well be a coping mechanism for my fear of going blind in real life, but girls missing their eyes or having them removed turns me on. Not so much seeing guys put their dicks in the holes though; for some reason that ruins it.

- I'd love if I could change genders at will - not merely superficially, but like a superpower in which I just change into the opposite sex version of myself. In all likelihood I'd never tell anyone and end up living a double life as a man and as a woman.

- Exotic piercings, especially the corset piercing. I've also made up a couple fantasy piercings that should theoretically be doable, e.g. a piercing through both shoulders of an armless girl, through which a bar could be inserted to act as a restraint or harness, or as a fixture for carrying something. Picture an armless barmaid who carries drinks to your table on a tray bolted through her shoulders.

- Debreasting, although in an odd way. I get turned on thinking about women losing their boobs, temporarily (followed by regeneration) or, even more so, permanently a la "MS Topless." However, I also remain acutely aware that living or having a girlfriend with no boobs would get un-sexy really fast. :\

- Decapitations. Similar deal to debreasting - I can go for either temporary decapitations or permanent ones, fatal or otherwise... but actual death turns me off. Sometimes I find it okay if a character dies in a really sexual way a la "Fountains," but usually when a character dies, even in an image, I end up getting emotionally invested and disliking the idea. I couldn't possibly fap to someone dying in real life.

- Some forms of BDSM, particularly the idea of having a subservient partner who gets off on doing my bidding and being controlled. I imagine I'd be a gentle master, eschewing violent punishments in favor of psychological torment, but I have no experience to speak of in this department :C

- Tracheotomies. Tracheotomies as a result of smoking turn me off due to smoking being involved, but I like the idea of having a sub who only gets to talk when I close the hole.

- Oculolinctus. I mentioned eye stuff earlier, and this is a worthy substitute for the more intense stuff, and thus something I'd love to try in real life sometime.

- Split tongues. I've never met anyone with one, but I imagine they would be epic kissers.

- I can sometimes get turned on by brain guro or heart guro, but it depends on the specific image or story.

Whew. That's all I can think up at present. I seem to have picked up a lot of fetishes since I started frequenting this site. I'm such a perv... xD
