I have been dating a girl and 3 days ago recieved oral from her. The very next day within about 24 hours or less I noticed what appeared to be a pimple on my penis shaft. It didn't hurt or itch, it wasn't filled with puss and it didn't pop open. It was red and appeared very much like a pimple without puss and the skin around it was dry. now it has been 3 days and it appears going away. The skin around it is still dry there has been no puss and it still has not popped open and the skin around it is dry I was able to peel a dry flake like when a cut is healing, not crust or a scab it's hard to explain but sort of like dandruff looking. There are no other bumps and I do not have any symptoms. Could this be herpes. I have never experienced anything like this. I have pictures I just don't know how to post them. Thank you for your time.
