Sex doesn't feel good for me help?

Aj
So I have had sex a good amount of time my ex and I did it a lot and have been with 2 other guys in between them and now! And it has never felt good for me! I didn't really care before but now that I'm with my new boyfirend I thought for user that I would enjoy it because there is so much sexual tension and passion between us all the time! But I still didn't like it! All I feel is like I have to pee the whole damn time! Is there something wrong with me?
