I think if the guy is truly into you, then there's no reason for him to look elsewhere...you're not freezing him out of sex altogether like many girls do. You do almost everything except that, and if he's satisfied, there's no reason to worry.

I would also venture a guess that the guy you were talking to had ulterior motives for making you second-guess your relationship. Guys are not only horny, but they can be manipulative when it comes to hooking up with a girl they like...in short, I disagree with his quote because I think it was a loaded statement...it can't be applied to all men.
