I have not been tested for herpes so please don't tell me to get it looked at cause i know that. But i have 5 red dots in a line around the head of my penis. Now if this was herpes how long does it take for them to become blister and crust over? I'm starting to think it's just a rash. My last sexual encounter was like 50 days ago. I saw the dots like 7 days ago and they haven't done anything yet. Opinions anyone?
