Can't Orgasm...What's wrong with me??

I've never masturbated and I've only had one sexual partner. 
And I've never orgasmed, I don't know what it's supposed to feel like. I feel like there's something wrong with me because I also don't have much of a sex drive either.
My boyfriend feels like it's his fault that I can't orgasm. But it's not that he doesn't satisfy me, I just don't orgasm. 
Is there something wrong with me?
