Can't Give My Girlfriend an Orgasm

"Help! I cannot give my girlfriend an orgasm no matter how hard I try. I have tried everything and I mean EVERYTHING. It is not totally my fault. She says that she’s only had like three orgasms in her whole life.

I have even tried to get her to show me how to touch her clitoris, but she says she does not like to play with herself. Is there anything I can do to give her an orgasm?"
