HELP S.O.S

So I'm having sex with my boyfriend and this has happened a couple of times but it's like I can't enjoy it as much as he can. Don't get me wrong I'm completely attracted to him and I love him a lot, it's just I can't get the most magical feeling everyone claims you have during sex. The only time I orgasm is when I'm on top but that's it. Is there something wrong with me? Even when I masterbate I can't orgasm, I've tried everything from rubbing the clit in many ways and motions to fingering but still nothing.
