So abouta a month ago I noticed a dark brown -ish patch on the side of my penis shaft, and I attributed it to excessive masturbation because i've sustained tiny little grazes and what-not through that before. In the past couple of weeks however, I've noticed more and more of the patches around my penis shaft, all the same colour (dark brownish, sometimes the top of my foreskin is purple or red when particularly irritated)
I was thinking (hoping) that it's just some bruising, but none of the patches hurt (not characteristic of a bruise.) The good news is that there's no discharge, funny texture or pain like i said.
Does anyone here know what it could be and how long it would take to go away? I'm embarassed and quite worried
