Background info: I'm 24 years old, male, gay, American, and haven't been sexually active since I was 18. Never had any problems with ED when I had sexual encounters in my teens but I've developed what I believe is very severe PIED over the last 4 years or so. I often can't even get an erection to porn anymore and when I do it's not nearly as full as it used to be, and it never lasts the entire session. I've been masturbating to porn since I was maybe 13. But all of this pales in comparison to something else that has been really worrying me: I'm afraid, terrified, that all the times when I masturbated my mostly flaccid penis with what was basically a death grip have lead to me irritating my penis/urethra to the point where I might have permanent trauma like a urethral stricture or something. For about two months or so I've noticed I'll sometimes have a painful ejaculation when masturbating, and I've noticed after I'm done peeing I drip slightly more than I think I used to. My urethra has also just felt plain sore for a while, and seems to be worst when I 1) masturbate for a long period, or 2) abstain from masturbation for about a week. Polar opposites, I know. ANYWAY I went to a urologist recently for my ED as well as my varicocele (yes, another problem down there, not to mention the fact that I have giant squiggly veins on my penis that I didn't used to have until fairly recently.) He basically was convinced that the ED was in some way psychological and gave me a low dose ED med prescription to take daily for a while. But when he was examining me, he stretched out my penis rather forcefully and I had a pain in my urethra, which he seemed kind of surprised at. It's the same place the pain always happens, kind of like where the head of the penis meets the shaft. I'm scared that I have damaged myself completely and have no hope of ever having a normal sex life ever again, or that I will need major surgery to repair something. I didn't tell the urologist all of this, but I did say I was concerned that I felt pain when he examined me, which he didn't seem to think was that big of a deal. Anyway, this might be a TL;DR for a lot of people and I get that, but I'm just so worried about this. I've been trying NoFap again after a while, but relapsed recently after a 9-day streak and had a 7-day streak a week or two before. Highest streak I ever had was 14 days back in 2016. I'd normally never post in a forum like this so please understand how desperate and defeated I feel about this.
