I'm 24 and I have ED, now

Hey all, first step's admitting it, right?

I need some help, friends. Here's my story, if you have a minute.

I dated this girl for a while. She was a virgin and we basically did nothing but dry hump and make out the entire time we were together, I thought I was falling for her so I figured it was worth the wait.

What actually ended up happening was an utter collapse in the relationship and a four month overload of furious masturbation and a massive backup of blue balls.

To keep it short, every time we were together, I'd get hard, then lose it because it would never go anywhere, I'd go home and beat off, rinse and repeat x243.

It's been close to two months since we broke up, I started seeing someone again and now, it turns out, my dick doesn't work. At all. I get turned on and lose interest in a few minutes, lose the erection and gain a lot of frustration. I don't know if it's entirely because of all the porn I've watched or the boners I've lost during this stint but I've never had a problem like this before and I've been watching porn and masturbating since I was 13.

I'm currently fully sober from porn and masturbation for 3 days as my first step to fix this stuff.

Can someone who can relate please give me some advice?

Thank you

TLDR: HELP
