Well, thanks for all the responses so far...I really do appreciate them
I'm going to give you guys some more background info that may help:
I kinda told him how I felt about him already...and he seemed cool with it. We still talk on the phone all the time. He always invites me over to his apartment, but I never go because it always turns into an occassion for him to try to make a move (and I'm not sure how far I'm ready to go with him yet)...at least that is what it turned into before I told him how I felt.
Also, here's another thing I'm curious about...maybe one of you have been in the same situation...
How do I tell him that I don't want to fool around with him because he is a little dirty? And I have no idea how to ask him to get tested without making it sound totally rude. Any help on this?
