I am an 18 year old male, in relatively good shape (5'11, 170 pounds). Recently I started a new relationship, and a short while after I started to experience erectile difficulties. I have difficulty getting an erection, keeping it and when I do get one I seem to suffer from premature ejaculation. I am confident that I do not have a sexually translated infection.
It first occured about two when I was incredibly intoxicated, so I figured it was probably just that I was too drunk - none the less I kind of got nervous. Since then the problem has been getting worse. At first it was just trouble getting erect enough for intercourse - I could still get part where there. And then I started having trouble even masterbating, I still can but it takes a long time to get ready. The last couple of times my girlfriend has been in the mood I haven't been able to get it hard at all.
I have had no history of any of these problems. At my age this shouldn't be happening, especially not so suddenly, what can I do to deal with this? Is it just that I'm worrying too much? If so what can I do to get back to the way I used to (and should still) be? I have no access to a doctor so anything you can tell me is welcome.
Worrying is the worst thing that you can do, as this will build up stress and everytime you are about to try to have sex you will be anxious about whether you can or will perform.
At your age is is not unknown to not last a long time before climax, and this is about practice and experience. So if this is causing you to worry, the effect now maybe to prevent you getting hard, if the two are related.
The one thing that will not really help is alcohol, even at your age. As alcohol is a suppressant (or is it depressant?) a couple will calm nerves but a lot will affect your whole performance.
Next time you think sex may happen, try to prepare to be relaxed, not stressed, with no worries or cares, including things like making sure you are comfortable, not likely to be disturbed etc.
