I am 22 and in a living hell. There is no one i seen that cured their hard flaccid. Because no one even knows what it is or what is the cause of it. My penis is constantly retracted and whenever I stand up it gets really bad and only goes away when I lay down which I've been doing the past 3 months to get relief. Sometimes when I pee it goes away but comes right back and it always hard. Only lying down in bed all day gives me relief. I am in a living hell and I know this will never get better again. And NoFap only makes it a lot worse I tried. There is no hope and my existence is literally worthless at this point. My life was sh*t before this and it's only worse now. Beleive me I'd rather shoot a bullet in my chest on the non heart side or throw a glass bottle at myself. I will never get rid of this and will be in hell for the rest of my life and I'm only in my early 20s. No hope for anything and my existence is nothing but pain and suffering and knowing there is no hope for penis to ever be normal again. All the doors are closed and I have basically a shackle around my neck without there being any hope.
I improved my hard flaccidity a lot, I did manual traction in a sense that I felt my pelvic floor stretch up to the anus, short 30/60 second sessions, and pelvic floor kinesiology as well.
retraction I still have, the loss of elasticity has not yet been discovered how to solve it I think. But before, my flaccid penis was a wooden stick.
You are young, I had it at 24, today I am 30, and if there was a cure / treatment at 35 I would be happy, at 40 I would also accept it although it would affect me more.
It is not the life I dreamed of, but you can still live it, there are many worse things in life.
I haven't completely cured mine but some things that have greatly helped are heat therapy, traction, and pelvic floor breathing exercises that I do with my pelvic floor physical therapist. I would highly recommend seeing a PF therapist if I were you. Keep fighting brother.
Traction, heat, abstinence (masturbate one a week, ZERO porn, never binge). Consider ALCAR, pine bark, and nattokinase.
Pelvic floor exercises might help too. Keto and fasting worked for me too and still work.
