Orgasms hmm...

Angelique
Alright everyone, help me out here. I am not able to orgasm during sex with my boyfriend! I've tried everything! Different positions, vibrators on the clitoris, EVERYTHING! I am able to orgasm using vibrators by myself though... My boyfriend feels bad because he feels as if he can't please me! I do enjoy sex, but I can't orgasm. Does anyone relate? Any tips???
