Hi all,
I'm 19 and just recently lost my virginity (I've had enough opportunities being in college but haven't felt comfortable until recently). I can't seem to cum in front of or around a girl. I can masturbate and orgasm in a couple minutes if I want to (with some turn-on material), but with a girl it seems impossible. I also Loose my erection 10-15minutes into sex and I can't get it back, Oral sex can give me an erection easly, but when I try to have sex it disapears 10min later, it's very frustrating.
Oral sex, hand jobs, and sex all feel good but nothing excitingly good. I'm wondering if I'm too used to masturbating and pleasing myself that it's making it hard for me to enjoy it when someone else pleasures me? I know I can cum quick, and my first sexual encounter I was afraid I'd be a two pump wonder, but it was just the opposite- got hard and stayed hard, but just couldn't come and it became depressing and made me focus on 'i have to cum'.
Needless to say, I'm a bit hesitant to engage in sexual activities. I'll start taking some advice here and forget about it; if anything try enjoying it more and stop thinking about what ISNT happening and just let it happen. If anything else, I just want to be able to keep it up long enough for the girl to atleast get off during sex

and worry about myself later.
::sigh:: part of me makes me think I waited too long and I've de-sensitized myself to sex with anyone but my hands
Any help would be Greatly appriciated .. I have a new girlfriend that I trust and I still have the same problem with her, she thinks its her fault and she's totally cool with it. She's kind of new to everything and wants to help me fix it. I really want to fix this so she dosen't feel like it's her falt.
Thanks
