Hi I made an account here to post my experience in this thread.
I have been dealing with this same issue.. For 4 years. It happened one day while I had been masturbating for awhile. I felt a sharp pain at the base of my penis on the left. After that my penis instantly deflated and I could not get it hard again. I was very scared and didn’t know what to do.
The next day I noticed all the sane symptoms. Penis head had shrunken considerably even when flaccid and felt cold to the touch as well as being a more pale grey color. I could not gain an erection and had much less feel in the head except for some pain when the very top would touch my pants or bed while sleeping.
I tried just not touching it for months but still no change whatsoever. My penis is literally half the thickness it was due to no glans and spongium engorgement. If I grip the base hard I can s K so force and trap some blood in there and almost regain full size but the moment I let go it shrinks dramatically.
I’m curious if you’ve found any solutions yourself yet Frizzle. This injury has also destroyed me in terms of confidence and sexual enjoyment and I don’t know what to do.
