I have had several(5-6) unprotected partners over the past 6 years, all of them girlfriends, except for 2 being acquaintances. I have been in a monogamous relationship for the past 9.5 months. About 1 month before my current girlfriend and I started dating, I had a one night stand with one of the acquaintances(unprotected). Before this one night stand, I had been tested for Gon/Chlamydia/HIV/Syph/Herpes, all negative. I failed to get tested after my exposure 10 months or so ago. My current girlfriend and I have been having sex since August. We have had our slip ups of unprotected sex, but most of the time we use protection. Not for disease prevention, but for pregnancy prevention.
Well last week I started to feel a constant urethral discomfort. For the first week, there wasn't any burning with urination. However, the past day or two, there has been some mild burning during urination. Also, the mild irritation, discomfort in my urethra persists. In the first 5 or 6 days, there seemed to be the feeling if not getting all of the fluid out of my penis after urination. It seems to be a bit better then it was 5 or 6 days ago, but the there is still some irritation there. There hasn't been any discharge that I've noticed, no sores, blisters, no redness in the urethral opening.
I am now very worried I might have infected my partner with something like chlamydia or Gonnorhea. I understand that most chlamydia/gon infections clear up on their own in men within a few months. However, now I'm scared taht I gave it to her, she'll think I've been unfaithful, which isn't the case. I also know she has not been unfaithful, we have an amazing relationship. Assuming she hasn't been unfaithful. About a week before my symptoms, we had unprotected sex. This makes me think I somehow contracted some sort of non-chlamydial NGU from her? Is that possible? Also, she performs unprotected oral sex on me at least 2-3 times a week just in case that might have anything to do with it.
