I recently tried to have sex with my girlfriend but couldn't get an erection, we have subsequently tried several times, but nothing. I go limp just before penetration. Whats causing this? Whats the solution? I'm 18 years old.

Response
This is nearly always caused by over-excitement rather than any underlying physical problem. Have a look at our article on impotence and view some of the useful websites on the subject. With time and patience you should be able to maintain your erection.
