I have a a darkish scab like thing of my penis shaft, And also at the base there is 2 other dark scab type spots. They look like dry skin, but when I get an erection they rip or open. Also on my testicles there is a white spot, it looks the same as the others but white. They look kinda like dry spots but theyre not. I have no pain while using the Bathroom of no discharges. But I do feel a slight tingling down there. Help.. pretty scared
