Hey, this might sound a bit stupid but I'll just out with it...
I'm 21 and in good health. Last week I was with a girl and things were getting a little heated, we were masturbating (each other) but while she climaxed fine I just couldn't. I was with her again a few nights later and we ended up having sex. It was my first time, and although I've heard things about people lasting not long at all on their first time we were at it for a while and I still couldn't.
I'm a little worried about this because I'm fine if I masturbate alone. This normal or am I some kind of undersexed moron?
Don't worry about this bud, its common for some of us to have this experience the first time out. Your penis is very used to your masturbation technique. Grip, speed, location...all of that plays a role in your ejaculations. Sex is very different and it may take some time for your penis to respond to the feel of her vagina. Moral of the story..keep trying! Sex takes two people working together and trying new things. This may also be about some nerves so don't get to anxious or worried about it as that will only make things worse!
Heh, cheers lads, I'll try not to let it get the better of my thoughts. Luckily enough she's a wonderful girl, and more experienced than me so I think she knows it might take a little time. Thanks for the help!
