1) Male.
2) Heterosexual.
3) A lot. Mostly anime girls, hentai, and associated things (i.e. tentacle sex, animal/monster girls, futa), but also things like anal sex (on myself and a partner), breast milk, extreme insertions and things like body inflation or expansion, though not to a great degree. I also have a fetish for petite women.
4) I've never had a partner, but I do experiment with myself every so often. There was this one time with a can of Diet Coke...
5) Scat, vomit and violence, including gore. Don't have any problems with urine, actually; it's sterile when it leaves the body, so it's not really that gross, as long as it doesn't smell. Basically, anything that could make someone sick or involves hurting someone. However, I can't stand the idea of being a submissive partner, either; it makes me feel insecure and helpless, and being bound is completely out of the question. This is kind of a problem, as one of the things I'm into almost requires lying still as my partner... does the work, I suppose.
