This picture allows you to see it better
Well I would not masturbate as the friction can cause further irritation. It does not look concerning. Do the bumps ever turn to sores? Does it burn to pee? Also do you use lube when masturbating and if so, water or silicone based? Do the bumps ever swell up? How old are you? Do you use soap when washing your penis?
The small bumps are a natural part of your penis, some men have these very distinctly, other cannot see them at all - these are what you have.
Respond to g2020 ’ s questions …
I have never seen sores which is a good sign and it does not burn when i pee. i do use water based lube when i masterbait. the bumps only swell up when i masterbait. I am 20 years old. And i use soap when washing my penis. it is just small bumbs thats swell when i masterbait. Also the redness around my penis head is a little tender (feels like raw skin), but it is not that bad at all.
i updated some information in my response to g2020. could anyone give me any ideas on what it is based on the updated information.
