These past few weeks I have notice that I have these black scabs things on the shaft of my penis at first I thought it was just from masterbating to much then I got worry that it was something else but after doing some research on the Internet I saw that I might have been right the first time. Something about bruising or cut the skin tissue. I know it can t be an std because I haven t had sex but I m.planning to but I just want this to heal first could you recommended what I need to do and use for this to heal and how long would it take.
