What's going on?! And what is he thinking? Please help! Sticky situation!!!?

I wouldn't be that worried about it. he doesnt seem like hes that kind of guy that would get upset at not getting any. Be open and honest with him next time you talk to him. Having too early in a relationship can ruin it. I think you're doing the right thing. Don't feel pressured into doing it just because your roommate it willing to. Guys will appreciate the fact that you respect yourself trust me!!
