Dr handsfield. First thanks so much for this service and your prompt replies.  You may remember I asked recently about symptoms I developed days after an oral encounter. A scratch sensation on the side of my penis and then urinary symptoms. All tests negative then 5 weeks later burning prostate pain that has not remitted.  I had been catheterized 6 weeks before the bj  for hernia surgery.  Given the timing …6 weeks…it seems cath infection less likely than oral infection so wanted to follow up.  You wrote an article where you stated that half of men diagnosed with NGU will never be able to pinpoint a bug from the infection. Chlamydia etc account for only half of the infections. The others are never found. Good article.  You also said urea and myco plasma cannot be contracted orally. But I found a study that said it could showed a case of oral infection by UU see 

A case of oropharyngeal Ureaplasma urealyticuminfection in a human immunodeficiency virus positive bisexual male co-infected with human papilloma virus and Treponema pallidum.  

Welcome back to the Forum.  FYI, Dr. Handsfield and I share the Forum and on this occasion I happened to pick up your questions.  In preparation for replying, I reviewed your earlier interaction with Dr. Handsfield and agree totally.  As an FYI, in the 1970s the role of M. hominis and U. urealyticum was intensely and aggressively studied and failed to demonstrate a causal role for either organism as a cause of urethritis, including NGU.  Both organisms are normal parts of the urogenital flora and demonstration of their presence is a coincidental demonstration of normal genital flora, not identification of something that needs to be treated. Further, with treatment, will these organisms may be eliminated fo a period, as normal flora they tend to recur.  Case reports such as the one you have found are suspect and of little relevance to your situation.   ---

Thx DR Hook. Such a great service you provide.  Sorry for the follow up but I am about to pull out the hernia mesh in an effort to stop these terrible urinary symptoms.  Do want to be sure it’s not std related.  Two things.  I had a very definite scratch/paper cut sensation on the side of my penis the day after the oral encounter there was no abrasion of any kind.  Wondering if that symptom is a sign of any infection you are aware of.  2.  If this was a catheter infection from surgery I find it hard to believe that symptoms would appear over 6 weeks after catherixation.  Any thoughts?  The symptoms came on so directly after oral exposure that it’s hard to ignore. By Non-mg urethritis I trust you mean non microgen genitalium?  There are whole Reddit boards  boards full of people claiming prostatitis from oral urea plasma infection.  

The "scratch/paper" discomfort you mention on the side of your penis is not a recognizable STI symptom.  I will however point out that on occasion when clients are focused on looking for abnormal symptoms they sometimes become aware of otherwise normal sensation which ar mistaken for pathological processes.  Such symptoms are often described an "itching" or "scratchiness" and are present unless a person is distracted.  No sure if this is what you are experiencing but the symptoms you describe raise no concern for STI.  .  Further , STI symptoms rarely develop within a day of exposure as take time for the infectious process to get to the point where symptoms are detectable.  ---
