I have a few marks on various areas on my forsekin, which are light greyish/brown in colour. They are spread around a bit
on the foreskin surface - a couple
of light blemishes
on the
top side, but more worryingly a group of three around the right, on the underside of the glans, which feel ever so slightly raised as i run my finger across them.
I am an extremely frequent masturbater (sorry!), and have been for many years.
