Your sexual frustration levels are too damn high, no matter if you're a testy teenager with high hormones or a stoic saint with no usual taste for sin or anywhere in between. The source of your need can be just about anything: you've never met anyone of your age/gender preference before, you've wanted this particular person forever because of a colossal crush, you two have been together and you want to take things to the next level, there's been physical distance between, it's been a while since you've gotten any human contact of the sweeter kind...or you've never gotten any. Anyway, you're in a situation that's just too tempting -
Oh, forget resisting. You're not in the mood for that. And apparently, the mood they're in is open to you. Go ahead, what could hurt if you instigate (or let them instigate) and let off some steam?
