I was just wondering, since I have masturbated a lot since i was younger & still some to this very day, would this be a irritation issue from it, balanitis, yeast or what? My doctor checked me for std's & I have been cleared of those. I haven't been sexually active in way over a year so, I have attached a picture. Would like to hear from you as soon as possible. These spots come & go with friction or from masturbation more than anything.
