Here's the thing: all I want to do, although it may sound very petty and stupid, is try dry humping. I've never been in a relationship/done anything with a girl in my life.

So basically, I see a lot of hot girls in my gym/around my campus, and I reeeeally want to try dry humping (where she's on all fours - and I'm from behind, like in the picture).

Honestly, I don't know how to go about this. I don't know where to start. I feel as though I'm not attractive enough for any girl to want to do stuff with me, but this isn't anything really "personal." People grind in clubs all the time.

Please note that I don't want any relationships or anything like that. ALso, how would a girl react if I asked for her number (and IF I got it), maybe hang out a bit later and ask her to try dry humping? Just say that I really want to try it, but never could? Would she be inclined to oblige, since it's not like actual sex or anything, and it's very "non-personal?"

Any advice on how to try to get this to happen?
