Oh gosh!!

I'm at my ex boyfriends house. He left to go run an errand and asked me to hang out here till he got here. So me being all cocky and what not told him he better hurry up. So he left right? Well I'm sitting here watching tv... I already done a walk through his house and was being nosey and what not. Well I'm getting nerves, because he kept saying "Fuck you" because I was talking some shit, not being hateful but picking on him and he jokingly said that. So, I of course said "Fuck you too!" And he kept saying "You'd like it", let me go ahead and establish that we dated for roughly 3 months and it was about 4-5 years ago when we were in high school. Well I think I'd really like it to be honest but I'm not going to tell him I want to. I'm a girl, so I'm going to beat around the bush about that. Well I snapped back and said "Uh, I think you would like it more than me"' and he said back to me "I think you would". Well it boils down to him wanting me to make the first move and then as we can imagine all hell will break loose. I've never done anything with him, we just kissed when we dated. So you can imagine how nerves I am to do anything else.
