Did I contract mycoplasma genitalium or some other infection?

[Weakfool]

I'm a 40 year old male. In November of last year I made the mistake of receiving oral sex with a condom from a sex worker. She stroked my shaft and also rubbed the space between my scrotum and anus. Later that evening without a shower, I masturbated with anal play, using a condom covered handle of a large wooden spoon to try to stimulate my prostate. The following evening I began feeling pain in my left testicle. I had gonorrhea in the past and remembered the sensation was similar. I immediately went to the pharmacy, and took 500g of Cipro and 2g of Azythromycin. (I live in a developing country with poor medical services and easy access to antibiotics) The pain subsided for a day but retuned. I then took a 1g IM shot of ceftriaxone. I also found a lab to test for Chlaydia and Gonorrhea. Results came up negative.  Then I was concerned that it was an anal infection and would not come up in the uretha swab. I took 10 days of 100g of doxycycline for 10 days.  No change. Since only the Azythromycin relieved the symptoms, I switch back to that for 10 days. Then I read that Azythromycin. The pain retuned after I stopped the medication. Finally I decided to trust a urologist here as I started having pain in my kidneys and bladder. He said I have a UTI and treated me with 12 days of cefixme, I think it was and sent me for an ultrasound of my kidneys and bladder and a urinalysis and urine culture.  The ultrasound doctor looked at my prostate and noted sequalea from a previous infection. Also that I was not emptying my bladder when I peed.Kidneys looked fine. No pathogens isolated in the culture, but mixed bacteria and lymphocytes in the urinalysis. The urologist then started me on three months of Bactrim DS once a day. I don't trust the medical services here. The urologist never examined my prostate and never gave me an official diagnosis for what I think is acute or chronic bacterial prostatitis. Shouldn't I be taking this medication twice a day? I know I'm not that young, but aren't I too young for prostate issues?  Is it possible that I contracted mycoplasm from the sex worker by having her saliva on my perenium for a few hours then unwittingly pushing that into my anus? If not, did I trigger some sort of prostatitis by trying anal play? I am about 12 days into the three month treatment and feel some relief, but symptoms are worse at night. Can I pass on an infection toy partner?
