I know this is probably a rare occurence for men but I'm having real trouble cumming with my girlfriend. She used to be able to do it by jerking me off, but lately it hasn't worked. I don't have the same trouble when I masturbate though.
well, sometimes my b/f has a hard time cumming because we've been doing it too much, so he needs time to uh,'recharge' if you will. are u talking about that u cant have an orgasm when u and yer g/f are having sex? maybe u shud change positions, usually my guy can have an orgasm better when its doggy or on top. not really when im on top. tel her how u masturbate, and let her do it the same way you do it. goodluck!
