I need help asking about Mens Health.?

On my hip is a Brownish Spot. Its not gross or like anything doing anything werid. It looks like a birth mark and its just been bugging me. But lately the same kinda color traveled down towards my genitals. Ive had the brownish spot for 4 years and the doctor says its nothing to worry about. But i need a 2nd opoin. It dosent hurt or anything also. But as i was saying the spot like spead downwards and its like here and there around my penis and even on the penis. But it dosent hurt as i said, and i havent felt anything different. Any ideas?

I would guess it might be a discoloration of skin due to an excess of melanin. There's really nothing you can do about it, but if it keeps spreading, you might want to consult a dermatologist. They are skin doctors and can treat your problem a lot better than the people on Yahoo.
