If you use the drugs , or inject directly..why is an erection of over 4 hours considered medically undesirable? Vascular damage?

Aside from possibly ruining the old boy permanently (I don't know exactly how) it aches like hell. After not having a hard-on for over 9 months, I injected and 3 hours later all I cared about was getting the bastard to go soft. It was not a pleasant experience.

Doc... our whole body relies on blood circulating. My guess is that blood flowing into the penis but unable to get out creats a painful problem. I hope it never happens to me.

Blood will form clots in the little spaces and kill your smooth muscle cells and rupture your little spaces. In other words, your penis will have a blow out. It hurts like hell. You'll never have an erection as long as you live. Other than that, they are no big deal.
You will know you are in trouble if your penis becomes harder, a bit smaller, and starts to ache like crazy. RUN to an emergency room. Run like hell! They see it all the time, no big deal for them. But if you want to save your penis, run.
Now, if you have been taking injections, your penis does NOT need to be back to its small flaccid state by four hours. As long as it's going down, you should be OK. If it is bendable, etc, blood is flowing. But a rock-hard erection at four hours is time to act quickly.

A hard penis that is cold to the touch is also a sign of blood not flowing in and out.

I was having somewhat similar situations, prolonged erections. I went to the emergency room twice. Finally, my URO prescribed me injections of phenylephrine. So now when I'm done, I give myself another shot to bring the ol' buy back down.

No blood flow in and out of penis= priapism. Left untreated= gangrene=amputation.
