I made it as far as I could - page 24.
Your problem is mental and not physical. You’ve seen dozens of doctors and specialists. You’ve got input from dozens of PE vets. All of them agree on one thing. There is no fucking way that you physically damaged your penis to the extent of your situation by doing 20-30 mild jelqs.
Read the book “The Brain that Changes Itself” by Norman Doidge.
I had a knee injury with a chronic pain condition afterward that lasted for 3-4 years. I worked with a physical therapist, who told me my leg had already completely healed in the physical sense, and all the pain was in my head. We’re talking life-fucking pain here. Can’t walk, wake up in the middle of the night kind of pain, with no relief for years not even for a single minute, that bends your soul and taints all of life’s relationships with bitter self resignation. IOW exactly the way you’ve expressed your feelings toward your condition in this thread. So when he told me it was all in my head, I had the same knee-jerk (no pun intended) opposition to that notion that you had.
I fought him tooth and nail on this for the first 2 years, all the while doing my physical therapy. Never believing he was right (although imaging confirmed it) or that it would work, not noticing much improvement. Well in the third year my pain began to “unwind” itself. And the way it happened left no doubt in my mind that my therapist was right all along. My brain had developed certain beliefs (on a deep neurobiological level that is indistinguishable from perceptual reality) developed certain behaviors, and thought patterns around my knee. It was protecting me from re-injuring it with these behaviors, but its way of protecting me was to flash a constant pain signal so that I wouldn’t use the knee. Its protection was worse than the threat.
Anyway, I say my pain began to unwind because it took another year or two for it to completely go away. Even as I began to accept on a conscious level that the process of overcoming the pain was the process of retraining my brain to correctly communicate with my knee again, it still took time. It took tends of thousands of repetitions of activities that SHOWED my brain at a subconscious level that my knee was OK. And it took gradual re-exposure because if I just tried to jump up in the air from the beginning - it would have caused a TREMENDOUS perceived pain in my knee that would have reinforced my subconscious protection mechanisms. So I had to eat away at this false subconscious belief my brain had bit by bit.
Anyway, I know your dick is not a knee so don’t call me an imbecile ;) . My point is that you’ve attacked this every possible way from the physical direction. If it were me and I were facing such a life-destroying situation, I’d be working all the avenues.
So if you’ve got nothing to lose, why not try progressively exposing your penis to the “threat”. Perhaps start by lightly massaging. Then some days or weeks later start lightly pulling on it or lightly squeezing it. Make the goal to prove to yourself that you’re not “re-injuring” your penis. Work your way back up to jelqing or if you’re not comfortable with that, maybe just some more forceful stretching. The goal being to expose your penis to considerable forces in order to train your mind that it is not this fragile broken thing that you’ve come to believe it is (on a pre-conscious level). Since the problem has been festering for years it may take years to unwind it. In other words you may still feel pain or numbness or less of erection as a result of the exercises, but as long as they are not getting worse (or recover to their previous levels within a few days) then you’re not losing anything but there’s some chance that over time your brain realizes the penis is not injured.
I know you said your initial symptoms were utterly inconsistent with any type of psychosomatic condition. But man, the spiritual and mental condition is unfathomably complex. Infinitely complex. Maybe you did have a real injury that first day. Maybe your mind perpetuated it on a pre-conscious level for all this time for some reason you’ll never know or understand.
That book recommendation will help. Trauma therapy techniques might help too. Hope this post helped somewhat. Keep an open mind. Always maintain hope. Try everything.
P.S. I now live pain free, but in the depths of my pain, that was just the smallest, faintest kernel of a dream that I hung on to with the tiniest shred of belief. Predominantly I had resigned. But as long as you believe enough to take the next step, and put one foot in front of the other, maybe years from now you’ll find yourself standing somewhere good again.
