Darkening penis

Here’s a concern I have about jelqing: What if the constant pushing of blood to the penis causes a reddening/darkening of the head/shaft over time? Has anyone noticed that their cock has darkened over a long routine? My penis is already fairly dark compared to the rest of my body and I worry about it getting darker. It seems that to women the most important feature of the penis is that it is an even shade that matches the rest of the guys body - or so I’ve read.

Yep it pretty much comes with PEing you will hear people on here call it discolouration. Do a search there are some things you can do to prevent / reverse it.
