I'm fifteen years old and for the past month its been growing more and more difficult to get an erection, and once I've got one it lasts no longer than several minutes. Very seldom do I get a full erection and maintain it till ejaculation.

I am sexually active, and it's the same thing. I do smoke cigarettes and drink quite a bit, I'm also a vegetarian. But as of today, now that I have addressed this a legitimate problem, I quit smoking and drinking and am now looking for vitamins to help with this. I'm in the proses of making a doctor's appointment as well.

DOES ANYONE KNOW What's WRONG? CAN IT BE FIXED? WHAT SHOULD I DO?

It might be your bodys way of telling you your heading in the wrong direction. Also because of the drinking you could force the onset of diabetes. That is also one of the symptoms.

15 and drinking and having sex all the time ?

Yes body is telling you to slow down

I'm having sex all the time. And even sober, getting an erection, keeping it and finishing just won't happen.
How long do you think it would be before I am functioning, if I cut out all the drinking and smoking?

Sorry I meant NOT having sex all the time..

Let me put it this way. You need to COMPLETELY change your life style. You need to immediately stop smoking, drinking and having sex before you kill yourself and/or get some poor girl pregnant.

You are breaking the law, you could wind up in jail for underage drinking, you are getting cigarettes and liquor illegally. And you may also be guilty of statutory rape.

You are a mess, physically and emotionally. And you need to change before you do yourself irreparable harm.
