Scars on penis head?

Hey, I have done PE quite a bit, few injuries, but I don’t think these have caused my next problem, I have noticed this recently but I have indentations in my penis head, looks like tiny scars, they aren’t major, but noticeable, I have drawn a picture of what i mean. I may have always had them, but not noticed them before PE.

The indents in the head are the same colour as the penis head, no pain or nothing… can just notice them because they dip in slightly. Like a tiny chunk removed with a stanley blade or something. Don’t recall no physical damage which could’ve caused it.

The picture shows where the marks are, may not be serious, im just a bit of a worrier. Please enlighten me someone, and please wait for the pic to be put on!

Thanks so much!

Can somebody please answer this question? It is worrying me, It’s had views, but no replies, Thank you.

I don’t necessarily know since I don’t have anything similar. But pinched skin does tend to toughen and/or callous. Maye there is some type of relationship there?

Would you consider them to be almost like same color micro-ridges?
