If you have spots on your penis, you should get it checked out by your doctor. There are several things that can cause spots on the penis, but only your doctor can give you a definitive diagnosis. Small pimple like spots around the corona are perfectly normal. So are spots around the shaft. If you have sore red spots or a rash and weeping then you should seek advice from your doctor. Some can be caused from sexually transmitted diseases and need treatment.
