I've had this irritated rash under my foreskin. It's not itchy or painful but has been there for three days. My last exposure was year ago and i did std testing for everything after 12 weeks. Got nervous about herpes so I did one for herpes after 15.5 weeks. Herpes test was negative. I went to a STD clinic last week and the doctor said everything was normal but I found this red location 3 days ago. I want to believe that it is just irritation but I need to make sure its not herpes so I can have sex with my current girlfriend.
