Keep taking pictures. Write down the date, time, and gist of any voice conversations with any medical or legal people on the subject of your penis. I’m serious; paper records can be your ally *if you keep them consistently*.
Bad: as far as I know, there’s no approved urological procedure that can help you. There *might* be something in plastic surgery, but it would be a non-standard procedure and probably prohibitively expensive. I have some nasty scars on my shaft; from personal experience, I know urologists want nothing to do with that, and the plastic surgeons want nothing to do with dicks. If it was a big scar on your face, no problem, but not there.
Good: there are skin-stretching techniques, mostly used by the “foreskin restoration” guys, that will give you enough skin to have a normal erection, but it takes a long time, and it won’t restore the nerves you lost; it just spreads the ones in the remaining skin out over the stretch.
