My penis is half pink (regular color) and half brown, I guess the brown half is due to circumcision scar as there is a dark ring separating. It's harmless I guess but I just don't like its shape which causes me shame when I'm nude for any reason, also I guess that it may cause disconfidence for me in having sex. I'm asking if it's possible to remove that brown part and make the whole penis fine pink or just without that brown part?
