I started to itch since December 24 and a doctor has said could be herpes . I have had my girlfriend for. A past year we have had countless unprotected sex. This time does this look like herpes or is it dermatitis? I have tested negative for syphillis. First picture is the cut I had at beginning after it was itching. Second picture is after 3 days. The penis head also have started to shed skin. Do I apply myoprcin at the head or the place where there is pus.
