I believe it might be sperm stains? [/INST] Degree understand your concerns went through your details. Discoloration of penis head depends on many factors like overall skin color, melanin content, exposure or any possible scar. This brown path you are complaining about should be inspected by a skin specialist to be able to diagnose your problem and treatment. Do you try to peel it off? Do not do any self treatments.
