Hello I m 24 years old. After having intense sex with this one woman, protected and unprotected for many months, I ve notice after a few months that I ve had discoloration in the color of black, blue, purpleish on the bottom of the right head of my penis . Also I believe today I started to see the same color start to appear on my shaft. There s no pain when I have sex, or when I don t. Everything works fine, no discomfort when I go to the bathroom. I just wanted to know why is my penis discolored. Is this something to worry about? Is there any way I can get my penis to the same color?
