What exactly is discoloration?

Discoloration is when your penis is with less blood flow, becoming white or is when your have too mutch dead blood on your penis, becoming dark?

I’ve always noticed that mine gets darker for about 3/4 of the length. Not sure what causes it though. Mine started when I started jelqing so I’m pretty sure that it’s not due to decreased bloodflow.

good question

Discoloration is a darkening of the skin. I would say it is very similar to bruising, as the result of broken capillaries.

It’s so weird.. I have never ever had any permanent discoloration. I have hung, jelqed, stretched, manual clamped and pumped. I’m feeling lucky! :)
