We've been dating for a month and a half, he won't touch me practically at all?!?

I'm a guy..and looking at your situation from a guy's point of view, the issue can be a number of things. He could be cleverly doing it on purpose(although I don't imagine many 20 yr old guys being able to successfully cope with voluntarily holding back from most forms of intimacy throughout all that time and opportunity), he can be nervous, he can have a private issue that has more to do with him than you..like questioning his uality or something. I'm sure by now you've checked your breath and all that stuff :-D to make sure it wasn't that. So maybe you need to have deeper conversations with him to get some clues as to what could be going on with him. You mentioned that you're used to guys moving kind of fast and that you're also rather aggressive yourself; at your age, that can and often does equate to brief relationships that are void of deep conversation. I imagine you wouldn't have this much bewilderment if you were one to particularly probe into a guys psyche when dating them. Based on how your question read, I gather that you've been kind of keeping your self in "guess" mode in efforts to refrain from "stepping on his toes" or intruding with probing questions. If that's the case..I suggest you go ahead a probe a little..it's become neccesary.
