Orgasim problems. HELP

Alyssa
Me and my boyfriend are sexually active and no matter what he does I can not orgasim. Not fingering, oral, or sex. I don't want to have to step in and stimulate myself just to get off when we fool around. I want him to be able to do it. Everything feels pretty good. But I just can't get there. I've never had this problem.  I don't get what it is. HELP
