m getting quite concerned because a couple of months ago i noticed a light brown patch on the lower right hand side of my penis. i thought it would
go away and assumed it was probably just some bruising due to masturbation ( i masturbate every day) However, the discolouration has now spread - there is some at the front, some round the top left hand side of my foreskin, and the initial patch i described it also spreading up my shaft. It is not sore, i have had no unusual discharge etc.
