No Orgasm with Sex

My bf and I had our first argument/fight over sex. He got super discouraged about not being able to make me orgasm saying it was all his fault. But no guy has ever been able to make me. I want to help him make it work. And I would like to at some point, but I don't want to discourage him more. I guess I'm just venting. But I wish we could figure it out at some point! I really want to show him how good he makes me feel instead of just telling him.
