Hi I’ll get straight to it. We have a non monogamous marriage and open transparent communication. I had a new partner on 12/18 and then again on 12/21 (the same partner). She is the only new partner either of us have had since our last full std check which was all normal. She said she is tested regularly. The encounters were unprotected. I tested on 12/23 for gonorrhea and chlamydia and both came back normal. I’ve not had any discharge or burning when I urinate but in the last week have noticed a burning sensation after I ejaculate. Of not I’ve also been doing pelvic floor strengthening exercises. I’ve never tested for Trich or MG, but could either of these be a likely culprit and do you recommend specific tests for these? Is burning from ejaculating without other symptoms common of Trich in men? Thank you in advance 

Welcome to the Forum.  Thanks for your questions.  I'll be glad to comment.  Pain following ejaculation is not a typical presentation for any STI.  They certainly are not signs of trichomoniasis and the only STI syndrome definitively associated with M. genitalium is urethritis, which does not cause discomfort following ejaculations.  I suspect the discomfort you describe is related to some other cause, perhaps your pelvic floor exercises.  ---

Just a quick update and quick follow up question. I continued to see the same partner but developed symptoms of discharge and re-tested and was positive for chlamydia. I was Rx’d 1G of azithromycin and my wife was treated as well. I have notified my casual partner and she too is being treated. Questions: 

Straight to your follow up questions:---

Thank you for the prompt reply. I greatly appreciate you taking time to contribute here . It’s very helpful 

Well I was hoping not to be back here but here I am lol. My wife and casual partner and I were all treated on 2/5 with 1G of azithromycin. Everything seemed fine. I had sex with my wife on 2/12 and casual partner 2/13 . Neither of them have had an outside partner . I woke up today 2/20 with symptoms similar to my initial symptoms. I’m assuming treatment failed with one of them or we had sex too soon and I was reinfected. 

As you know, this would normally be the final response as part of this thread.  As I mentioned in my initial reply, pain following ejaculation, which is the symptoms you described is not a typical symptom of any STI - are there other symptoms this time?.  In response to your questions:---

Sorry to be confusing. I contracted chlamydia from the casual partner. She did not know she had it. Neither she nor my wife had any symptoms. I had discharge and burning urine. All 3 of us were treated at the same time with the same treatment (azithromycin) . I had sex with my wife a week later and the casual partner 8 days later (so we all were a week out from treatment ). This morning , one week after resuming sex, I had discharge again. I’m assuming I was reinfected , meaning the treatment failed in one of them bc I know I responded . Neither of them have shown any symptoms the whole time. I guess my only question: 

I agree that, given the situation, reinfection is the most likely cause of your recurrent symptoms.  All 3 of you should be retreated.---
