I'm 21. I've only had sex with 2 guys (multiple times) and I didn't orgasm with either of them. They made me feel good, but I never actually got an orgasm through sex or touching. Could it be that they weren't putting enough into it to give me the pleasure that they got? Or could it be me? I can orgasm when I masturbate, but not with anyone else. What can I do to heighten my pleasure?
