Damn so many people already went over what I like, but yeah like Nik I can fap to a lot of things, I blame a growing tolerance level to porn from over a decade of wanking it to ever more extreme stuff. Though Guro is almost always a hard NO for me, even I can't like that stuff.
Hmm, but aside from that let's see:
1) Impregnation, always fun
2) Muscles on girls, love the Amazon look
3) Femmenine boys, love the trap look
4) Subversion of social expectations, as seen with the previous two who subvert the usual looks to be expected from either gender
5) Horse cocks, I blame Fen for this one!
6) Consensual sex is always good, I agree very much with Nik's "Happy Sex" sentiment
7) Cum inflation, just something about showing off how virile a charachter is gets my motor running.
8) As an extension of 7, I'd say creampies, which is why I dislike condoms in my porn
9) Gentle femdom, with some petplay, no need for a dom to verbally abuse me
10) Double dicks, for that anal and vaginal double penetration!
11) After sex cuddling, hell affectionate cuddling/snuggling/hugging at any time is always nice, except in the middle of battle I suppose heh.
12) Cervix play, as in rubbing up against it or penetrating it, I know that in real life that would hurt like a motherfucker, but in fiction it is very hot.
13) Futa and Shemales, a girl with a dick is great, never did see the appeal of cuntboys though.
14) Monstergirls/furries/etc., as long as its pretty I don't really care, or doesn't try to eat me...
15) Vanilla, even with my ever growing tolerance to depravity I still find vanilla okay.
16) Incest, though I lean towards the brother/sister and son/mother side, Dad being involved weirds me out.
17) etc. and futhermore.
Mind you I don't need these to always be there, I can get off just fine with lots of stuff that aren't my fetish, like if its my partners fetish and I'm indulging them in it.
