Can I get NGU from fellatio if she has no STI?

I have read that you can get NGU from receiving oral that is natural mouth bacteria.  So is it possible to contact NGU from your partner if we are in a monogamist relationship.  Could her "normal" mouth bacteria give me NGU?

Yes, it's possible, but if you've had an outside partner, you may have gotten it from sex, and that bacteria could be transmitted to your partner. At the very least, avoid sex for 7 days or until your medication is finished, whichever is longer. If you've already had sex with a partner, and possibly exposed her, then she needs treatment. If she doesn't get treatment, you'll just pass it back and forth between you.

Also, untreated, this could lead to long-term consequences for her.

I 100% understand that if I have NGU I can pass it to her and vis a verse.  I was just wondering because I read it can be caused by normal mouth bacteria, does it nesssarly mean it was obtained outside our relationship.

Nope, but if you've had oral sex with the same person loads of times without issue, and then suddenly had oral from someone else, it's probably from them.

If your current partner has been sick, though, that could change things. Things like strep, adenovirus, etc., can transmit to the urethra.

I read that Chlamydia trachomatis is the most common germ  Responsible for ngu, if I was negative on a Chlamydia urine test would this have detected that particular germ if it were responsible  if I did have ngu?

Yes, the test would have found chlamydia if you had it.

You received oral sex. That's not a risk for chlamydia.

Can we keep all your questions in one thread? I'm having a hard time keeping up with your risk, symptoms, etc., since you have a number of different threads going. Thanks :)
