I always think of myself as being pretty straightforward and vanilla, getting pleasure from the various visual & physical stimulations of sex, but looking back I have tried a few kinks over the past few years...
I've been to quite a few sex parties, so the whole group sex thing is quite a turn-on, done FFM, MMF, MMMF, daisy chains, even a FFFFFFFM once...seeing a room full of the sights & sounds of sex certainly spurs you on.
One very beautiful Polish girl introduced me to rimming, she just went south one day, it felt electrifying, I returned the favour too...I am keen to see her again for more. I also went down on a cute Romanian girl's exquisite rosebud, she squealed, but let me carry on.
I once had a girl squirt on me, I think it was pee...I'd like to try that or full-on watersports again.
A few girls have given me DTBJs, verging on a mild face-fucking...it would be good to take that all the way to completion.
Anal...yes, I'd love to break that taboo and do a girl up the wrong'un! It would have to be a turn-on for her too.
I have a few clothing fetishes...a girl in a summer dress with no knickers...a girl fully dressed who gets her tits out and pulls her knickers aside to do the deed are a turn-on...but any form of seductive wrapping from sexy lingerie to high heels always enhances the experience.
I quite like outdoor sex (in the summer). :
Filthy, dirty talk both ways...some girls love this and respond in kind, upping the sexual tension to fever pitch.
I guess I'm not that vanilla after all!! But it is more about being creative, trying different things and finding things that give mutual pleasure, rather than any specific fetish that I go looking for on every meet.
