I had sex Thursday and Friday after about 3 months, I woke up to spots appearing on my bell end, any idea what it could be seems to be getting worse
We can't tell without photos, but I would suggest a doctor's appointment to get the root of your problem.
i put another discussion up with photos if you could have a look please
The other discussion is here:
