I can't even look at him

My boyfriend and I are both virgins. We've been dating a few weeks and the past few times we've been together we've been messing around but haven't had intercourse. Tonight we were hanging out and he didn't have condoms. We were fooling around and we ended up playing the "just the tip". I'm not worried I'm pregnant, that's not what this is about. But not I can't even talk to him or look at him and I don't know why. If anyone has something to say or suggest, please.
