Wierd penis discoloration from drinking too much caffeine products in one day?!

At the bottom of the glands of the head of the penis, I noticed at first what seemed like brown dirt, thinking I could just rub or wash it off. Upon closer inspection I realized it looked like a mix between "spider legs" (but obviously on the glands of my penis head) and that of a possible blood clot or internal bleeding, or baggy eyes (but of course on the penis) or that if a sort of brownish greyish discoloration almost like necrosis of the discolored skin area due to lack of oxygen or constriction of blood flow or whatnot...

Compared to baseline photos that I took (when I had balanitis, which was a fungal issue, but that isn't what is the issue that recently popped up) it is obvious that this is different from my norm, deviates from baseline, and the discoloration is not normal and not something I used to have (even when I had the most heavy fungal/balanitis issues a while back , couple months ago, there was never any discoloration of any sort and nothing abnormal at those areas and spots etc)

During sexual arousal, the penis can take on a reddish, almost purple color because of the increased blood flow to its blood vessels and glands. But there are other potentially serious reasons why your penis might turn a different color.

The causes of penile discoloration can range from a zipper-inflicted bruise to penile cancer, a rare condition that represents less than 1 percent of cancers in U.S. men. In some cases, a change in penis color is a sign of a sexually transmitted disease (STD) or a noncontagious, harmless skin condition.

Penile discoloration is almost always a cause for a medical evaluation. It may end up being temporary and relatively benign, but you shouldn’t make that diagnosis on your own.

If the change in color is due to an underlying cause that’s medically serious, getting a diagnosis and starting treatment earlier is always a smart approach.
