When I was 18. To be fair it was a drunken thing, one of my (female) flatmates had a friend staying with us, and we were going out clubbing. Pre-drinking in our flat, we somehow ended up in a game of gay chicken (still not sure how that happened). Anyway, after none of us guys were particularly willing to play that, my flatmate's friend decided she'd kiss me, if her friend (my flatmate) kissed one of the other guys in the group. We were al pretty pissed at this point, remember.
Anyway, sad to say that's been my only proper kiss so far, although I've been kissed on the cheek or whatever plenty since then (and indeed before). It's just that that's my only 'proper' kiss. Ah well, I'm still young (only 20), I've got plenty of time
