Hello, in recent years, maybe over the course of two years, there has been increased discolouration of my penile glans (head) I'm an early 20's male and it looks like flat random patches of red and purple, more so on the left hand sude that the right of the glans. What could this be? It doesn't itch, hasn't cause any issues other than being unsightly. At times the discolouration is hardly visible, and at others it is obvious. Bevause it seems to be getting worse in the long run. I am increasingly concerned.
