i have had unprotected sex once in march, this started showing up in august, i pee fine, no burning, no pain, been masterbating every night idk if maybe thats why my penis tip is swollen or wrinkly, but also why is my penis edges so wrinkly !!
Just stop masterbating for a couple of days. Urethra seems irritated.
Watch for those wrinkly spots caz i have the same problem all over the foreskin.
If they spread go to a doc.
You need to get STD tested AND these visually checked
