I'm 25 years old, no medical issues.
A few months ago i started to notice a discomfort on the tip of my foreskin. It is a very annoying sharp sensation, as if my foreskin is being scratched. Also, i only feel it when i'm using underwear, or when I am lying on my stomach. It is like i have an extra sensibility on my foreskin, that manifests itself when the foreskin is in touch with something. However, my foreskin, aswell as my whole penis, looks completely normal.
I already had a consultation with an urologist, who told me that my foreskin and penis is healthy and 100% functional, without any apparent issue. Even so, he prescribed me a skin fluid to eliminate any potential bacteria and mucous from the penis. I did the treatment, but it didn't have any effect.
I'm writing here in the hope that someone has any guess of how i may solve this problem. All help will be welcome. Thank you!
