I have developed a little infection on my penis. I think I had some irritation on my dick after sex with my wife. (Actually, the irritation built on some irritation that came from too much masturbating.) I wore a jock strap today because I had some ball pain, which I am getting an ultrasound for next week. The jock really irritated the skin, causing it to itch quite a bit. I took off the jock and eventually went commando. That helped bring the irritation down. I wonder if anybody uses any cream or anti-fungal medicine on their dicks. If so, what?
