Hi, It’s been a week since I noticed these formations on the foreskin of my penis. I am 23 and uncircumcised. There have been slight itching sensation, and I have had jock itch in the past. Does anyone know what is it? Is it normal?
There are many things that this could be - the picture you have posted suggest these are something that are naturally present on your penis.
To help identify them further you could post several pictures taken in strong daylight to get a clearer view of what you have - also draw the foreskin back fully and show what they look like for at least one of the pictures …
