Hi there. I have a problem which is really getting me down now. When I am with a girl, particularly one I really like, I find that the only way I can come is through sex in the missionary position and even then it can take almost an hour of banging away before I come, leaving us both sore and exhausted. Oral sex or her masturbating me just doesnt work at all, but if I am alone and masturbate I can come no problem. Thing is, now my girlfriend is starting to think I dont like her. She's not on the pill and if I have no condoms and we dont have sex then I end up with very painful balls. Have any of you had this problem before and is there any solution? It is really starting to depress me now. Please help.
