I think maven is right - seeing someone sounds sensible in this situation. Especially since it sounds like you have the beginnings of yummy flutters and arousal and you don't understand why they cease.

personally i like sex LOTS. i had a really nasty sexual experience overseas about a year ago and for a couple of months i didn't want anything to do with sex but what actually fixed me was going back to someone i loved and trusted and having lots of fun with them. i dunno. it's all very individual.

i hope you can work out what's best for you. and really, sex isn't EVERYTHING
