Whats Wrong With Him?

Well me(15) and my boyfriend(17), have been together for almost a year.

We just had sex for the first time about 1 month ago. I really love him alot and I know he's the one for me, but I felt bad that I was making him wait for sex.

I know that men have sexual desires and I know he loves me. That's not the only reason that I did it. I did it becuase I was ready!

But we have had sex about 3 times and I don't want to do it too much, but I don't want to keep from doing it.

But it seems like ever since we did it for the second time he has been so rude to me and we have been arguing and fighting.

BAD!

But we always make up or talk about it then . . . the next day we are at it again.

I know he loves me though so I don't think he's losing feelings for me. He tells me and shows me his love for me everyday.

I just don't know why we have been fighting so much. We are much better now and we aren't fighting but we were for the last two weeks.

I don't know if he thinks something or if he has something on his mind.

PLEASE HELP!
