I got a problem, a real big problem.
About four weeks ago, I had my last erection.
Since then, nearly nothing. Nothing at all, save a few seconds every now and then. It’s pretty bad.

I have not had any desire for sex, porn or masturbation.
Could this shit be psychological? Or is it physical?

This shit is freaking me the fuck out.

I need some advice here.

Need more info...

Age, Substance use (legal or otherwise), etc

As in, no popping sporadic boners or you can't get hard when you masturbate? Have you knocked on some porn and tried to knock one off?

Age: 21.
Substance: Two packs a day. Very little drinking till two and a half weeks ago, alot since. Work alot, 60+ hours a week. Desk job.

What else do you want to know?

Nothing. At all.

You're just overdoing yourself, man. Impotence is extremely uncommon for guys our age and if you've never had problems in the past, it's doubtful that it's a medical problem suddenly now. Smoking can reduce your erection strength and so will boozing, thus 'whiskey dick'. 60 hours work, a fuckload of piss and two packs of darbs a day... It's not surprising that something's giving.

Chill for a bit, man, and everything will sort itself out.

The routine has been going on for the last 7 months. And it was never a problem untill now.

Exactly what i was going to say... sounds like stress and alcohol got to ya, just take it easy and you'll be good to go. The reason i asked about drugs is i know that some meds (legal) will do that, specifically anti-histamines.

Until now... the point is it happened. If you are seriously concerned, see a doctor, people on the internet can't see you, and its neat impossible for you to spew out every detail of your life....

Maybe you're not sexually active.
