Here is what happened to me:
Last Sunday I had a very painful episode of priapism. I was drunk the night before and had had a pretty intense week of kegels. When I woke up I had an extremely intense and painful erection. I have a very large penis, but I had never my seen it this large or hard, or felt so much pain down there. It felt like it was about to explode from the pressure. It was bad enough to cause me to vomit.
The erection lasted about 5 hours. I had to go to the hospital in pajamas because it was impossible to fit in any normal pants. They drained the erection with a syringe. It went down and my penis is fine now, but it has gotten slightly larger. The experience was horrible, but I can’t complain about the growth (I’d say probably .25” both ways?).
This is about the 5th time that I get an episode of priapism. It was by far the most painful. The first episode was also very bad and did not seek help, and my penis got bigger after it as well. The other episodes in between were much less painful and resolved by themselves.
I think every time it happened, I had done intense kegels or masturbated/had sex for very long.
I wanted to believe it was a cramp in my smooth muscles, but erections are caused by nitrous oxide induced relaxation of the smooth muscles. So I don’t know how to explain it. I don’t think it is blood related, because I had tests and my blood cells are fine.
I now wonder if it is possible to cause some sort of trauma to the muscles by overuse or prolonged very intense erections.
So I had a second episode today. Went to the hospital again.
My doctor did some research and he seems to think I have stuttering non-ischemic priapism induced megalophallus. He doesn’t know for sure what causes it. Non-ischemic priapism is when blood flow into the penis is excessive, whereas ischemic priapism is when detumescence fails and cannot exit the penis. In ischemic priapism, the trapped blood becomes hypoxic and the penis can develop acidosis or even necrosis. In non-ischemic priapism, some sort of damage or trauma, or idiopathy causes excessive blood flow into the penis, but the flow out is normal. This creates intense pressure inside the corpus cavernosum and can lead to megalophallus.
Non-ischemic however is not usually painful, but I have such a large erect size that my trying to put on pants caused the severe pain. With non-ischemic priapism, a full erection can be achieved from arousal, which was my case (I was aroused by the whole thing very much against my will and better judgement, but once I was calmed down, the non-ischemic (partial) erection seemed to be that, non-ischemic.
Usually, non-ischemic is not stuttering (occurring in episodes, 2 or more). I don’t have any trauma that I know of but he did mention that because I had such a large penis and my erections were so strong, my perineal muscle might be strong enough to cause damage or irritation when used for long periods of time (I like edging), which might trigger the priapism. I certainly agree with him on that one, as that seems to have been the pattern before.
As far as I understand, megalophallus or megalopenis is used primarily for malformities in infants such as in Prune-Belly syndrome or where megalourethra also occurs, and it is a measure of being 2.5+ standard deviations from the avg. Megalophallus in adults is used for a change or gain of size due to some other cause. I am more than 2.5 SD from avg in all respects anyways.
I am going to lay off any type of sex/masturbation/kegels for a while and restart when I feel I have healed.
For now the gains are still there, even more so after the second episode.
So that’s that.
