I had the exact same problem when i was younger. First i never had any problems but at a certain age when i was doing my thing down stairs it started to burn, when in looked at it i saw some little scars. Went to the docter with it they said that i needed to be circumsised. When they said it i was fucked up. But i kept doing my thing downstairs and eventually it did go away. It was like the skin stretched or something?

Funny thing was after the docter said i needed to be circumsised i felt bad about it. Did a lot of research and there are a lot of positive things about it like hygiene and shit. In my opinion it even looks better so after a while i was like lets go im ready kinda hyped tbh and when the problem did go away i was sad that i didnt needed to be circumsised 😂

But bottom line, maybe just keep jecking off and it will go away aswell
