The symptoms appeared about 2 weeks ago. I first noticed them after a masturbation session. The skin right underneath the head of the penis on the left side was very irritated and swollen afterwards, and I noticed a small purplish flat looking area, not really a bump, but more of a "mark', right on the edge of the head of my penis. The mark isn't hard or seems to have any solidarity to it at all.
Over the last 2 weeks the mark has remained about the same size and color, and doesn't want to go away or heal up. And I am still getting a slight burning and irritation underneath the head after masturbation or intercourse.
At other times, besides the "mark" being visable, there is no pain or irritation.
No penile discharge, or any kind of open sores with these symptoms.
