Can't Make Myself Cum.

Okay, I'm 21.. And I'm not sure if I've ever had an oragasm.. I mean when I'm having sex there are times I think I do.. I get really wet, but I'm never sure. I try to masturbate to make myself cum but nothing ever works.. I either get really bored or irritated from rubbing so much. Lol I don't really like to rub my clit myself, doesn't get me off.. What can I do? D: Help, I'm wearing my bf out. ):
