Brown & white patches on my penis for 10+ years, new one showed up.

*Old one, at least 10 years*

*New one* I'm 25 years old, I was circumcised with 4 or 6 years old, I can't remember. Could this be because of the friction masturbating on the surgery points of the circumcision? A new patch appeared (second picture), I don't know if this is serious, they don't hurt in any way. The old one (first picture) was like this new one, just brown, then it became white in the middle. What can these be? Should I be worried? Thank you.

Most marking like this are due to natural changes within the skin that change the pigmentation and this is very common, in fact this happens right across the surface of the human body.
The other circumstance that can cause this that can be controlled is if you sweat a great deal, so athletes, competitive cyclists and those who do regular gym workouts where sweat is a regular result, for example, can be subject to this.
Are activities like this something you have done long-term?

Thank you once again @Wee_Dugie@. I’ve actually been more sweaty than usual, so, this goes in accordance with what you said, but it wasn’t been something happening long-term though. Thanks once again.
