About 4 days after my most recent sexual activity, I developed several small spots on the skin of my penis. The spots are round with a greyish dot in the center about the size of a pin prick. Does this description point to anything specific?
Follow what Vance said. Dots and spots on and around penis are quite normal and we have a tendency to over examine after a sexual encounter which makes us feel guilty or anxious. Most probably its nothing serious or bad.
However just see a Doctor for examination and reassurance. Do NOT self examine please.
