Your inability to have a vaginal orgasm is not what's affecting your relationship. You are fine, and your body is fine too.
It's your boyfriend's attitude that's the problem here.
You're not only normal, you're actually part of the majority. About 70% of women cannot have orgasms from vaginal stimulation alone, they need other stimulation of some kind, usually clitoral.
If your boyfriend insists on feeling bad about something that's normal, common and out of anyone's control, he's wasting his energy.
He'd better spend that energy on learning what does get you off, and how to make that a part of love making.
If he learns how to stimulate your clit during intercourse, you'll both have great sex and a wonderfully intimate experience.
