No Orgasims wats so ever!!!!

well im 19 and havent been able to get an orgasim. When i masterbate i cant even get myself to an orgasim. My boyfriend has tried everything to get me to get an orgasim but nothing has worked. Theres times that right after sex i just cry because the lack of the orgasim...I just feel something is wrong with me! Also there are times that i feel that i want to pee and that kills my whole concentrasion, i avoid to pee on him. Could that be the orgasim????? o.O i dont think it is. Also, outside the bedroom, when im in public i sometimes hold my pee and i lose the urge to go to the restroom. I do this alot. Can all this pee holding affect me in not being able to get an orgasim????????? :$
