For the last few months I am worried about my penis. The glans appears dry, it has a thin layer of white flaky substance (maybe skin cells) which sometimes hurt when being removed. Also, there are a number of wounds/bruises that look like a blade is used to cut the skin in a straight line. It is quite ppainful. These things never heal completely. One wound heals and other appears. Im very much worried. Any suggestions would be very much helpful.
