Its been 3 weeks since my unprotected oral sex encounter and I've noticed that my urethra is irrtated and hurts a little. It doesn't burn when I urinate, but feels a little sore afterwards. Is this a symptom of herpes? I know its not clamydia or gonnorhea because I have been tested negative for those. I don't have any apparent leisons on my penis or discharge. I've been a little paranoid/ocd and I've been checking thoroughly for any out of the ordinary bumps or redness multiple times a day. Is it mokre likely that the urethra soreness is from handling and inspecting my penis?
