Hi Doctor,
I find it hard to believe that this is merely a coincidence. I made a stupid mistake and relations with a very high risk person and have been having symptoms ever since. I had to urinate 3 times during the night last night and the tip of my penis is inflamed. Is it possible I may have genitalium? I have read that this STI is difficult to test for and hence why my cultures and urine keep coming back negative. The symptoms of this infection are also exactly what I have. Discharge, burning, frequent urination.
Welcome to our Forum. I'll try to help. It is time for your to stop,worrying about having a STI from the exposure that you describe. Receipt of oral sex is relatively low risk for STI acquisition and your initial symptoms, particularly urinary frequency are not typical of STIs. When you combine this with multiple negative tests and multiple courses of treatment you mention, there is really no reason to continue to worry about STIs as the cause of your symptoms. I suggest you work with your doctor to evaluate other possibilities including prostatitis or the chronic pelvic pain syndrome (CPPS, it is well described on Wikipedia).
There is simply no reason for continuing to worry about STIs, to test, or to worry about the possibility of infection your regular sex partner. I hope this perspective is helpful. EWH
Also, occasionally I feel a pain on one side behind my left testicle.
Just to add. All my chlamydia and gonorrhea urine and cultures returned negative multiple times.
