So the tip of my pee hole is sensitive, feels like it's burning or stinging.left testical somtimes painful, and bladder pain. doctor thought i had a UTI so gave me Bactrim meds. after 12 days of pills, it felt alot better but still there. 2 days later, it came back. went to different hospital. there they tested my urine and found Nitrates in Urine and no white blood cells. doctor said this could be alot of things and they diagnosed me with Non-Gonococcal Urethritis. I feel good when I pee though. I haven't had sex in 4 months. when I did, I had protected vaginal but unprotected oral. ive been tested for stds and I have cold sores. does anyone have any ideas what I could have? or what are your thoughts? I don't have any bumps too. I'm worried because I just got a new girlfriend. could this be anything serious? I've read about some other STDS and im scared about herpes. i don't have any bumps or blisters though.
