Recently i had unprotected intercourse with a sex worker as my condom broke on its tip.
During the next few days i noticed a brownish coloration on the foreskin and around the tip of the penis, and an occasional itching sensation. I have no burning sensation as i pee, neither any discharge, also i took PEP medication for AIDS.
The brownish area has not increased in size and i can't honestly say that it wasn't there before.
I have consulted a general physician, that ruled out any worries regarding STD's. Even though i'm not absolutely convinced, i would much appreciate if you could perhaps identify possible causes for this in a dermatologist point of view.
