My boyfriend & I have been dating for a year & a half now & we were very intimate up until this last month. I'm 18 & he's 20. I know it's only been 1 month but thats a pretty long time for us. Usually he's the one always wanting to, & a few weeks ago I tried, but he came up with an excuse but i thought nothing of it because it was the first time he's turned me down. but within the past 2 weeks I've been practically begging for it & he just wont give it to me. We both are working on finding a place together, but in the meantime we're living with our parents so we dont get to have sex as much as it is because our parents are always home & it's just uncomfortable so we usually wait until we're alone. Well his parents went out of town for the weekend so we stayed at his place & I thought we were going to do it since we have the whole house to ourselves, but once i started touching him etc.. he was just getting mad at me telling me to watch the show on T.V. that we were in the middle of watching. He was acting like he was soo into the show as if it would never be on again.. & as a matter of fact, we had it downladed on a DVD so we could pause it!! but he just refused & it really made me mad so I went into the other room & went to sleep. Well about 10 minutes later he comes into the room holding me & apologizing so I'm thinking we're gonna do it, so again I try, & AGAIN I'm turned down! I just dont get it! He says 'it's not you it's me' but what does that mean? I'm a very attractive girl & I dont think that could possibly be the problem? But what else could it be? It's weird because in the morning when he wakes up before I do, he's always touching my body & feeling me up & down but then doesnt want to have sex! So if he wasnt attracted to me he wouldnt be all over me, right? Nothing in our life has changed within the past few months, so he's isnt stressed about anything.. he gets everything he wants! So what's the deal? No matter what I do, he stays soft! I do all the things he used to like & now it's not phasing him! Sometimes I start kissing his neck or touching him when he's playing his Xbox but he just gets sooo mad that I'm making him 'die' & then I end up getting mad that he's being so anal so then I just go away! We never used to have this problem! No matter what he was doing, he'd always stop just to have sex! Now if i interrupt him, he snaps! He also used to love taking showers with me, even though I sometimes didnt like it becuase I simply wanted to shower & get out, but now he never wants to shower with me, even when I ask him to. He isnt really acting any different, he's still cuddly & playful with me, he just wont have sex! & recently while I was on my period, he would say to me how he can't wait until I'm off so we can do it & all that stuff but when I did end, we actually did start having sex but he went limp & I just dont have a clue in the world why! I didnt say anything but he ended up apologizing to me so I ended up asking him what the problem was & again he said it wasnt me it was him! So I Asked what about him? Whats wrong.. & he just had no answer. I dont know if i should keep trying or just lay around & wait for him to want to. Because I dont want to make him do it! I want him to want to! What Could Be The Problem?
