NEver ending cycle of male pain , please help me if you can

[Plzhelp1o1]

I'm a 24 year old male a year ago i

Had unprotected vaginal sex with a random girl

Within the next week had pain in testicles

Went to get tested , negative for all stds , I had to do the urethral swan myself, thought I cause stricture but after 2 cycoscopy no stricture(tested repeatedly from a clinic-all negative) from that time on I have(I got extreamly sick with flu like symptoms 3weeks after the sex-thought I had hiv,that's a different story but thought I should mention)

discharge painful urination, frequent urination . Burning at the tip,Couldn't ejaculate ,painful erections ,Got tested many times all negative.(rarely feel my but burns like I ate spicey but that doesn't happen often)

One year later Been to 3 uro had 2 cycscopsy everything seems fine. Sysmtoms are still there.(at the moment on ceftin and mainly have urination problems and discharge)

Blood urine sperm and prostrate fluid tests all fine .

I know I would be diagnosed with non bacterial prostatits but it can't be because this all happend after the sex with that girl. Before that I never had any any any issues burning or urinating.
The first uro I went to was a crook, waisted month for nothing ,the second checked prostate and said it was inflammed and mushy-prostatitis , he started me on doxy and when I told him it was slightly helping but I need more he told me he can't help me.. The third uro(world famous) has not checked my prostate ,no exam .. He did a cyscocpy and said EVERYthong is fine (this was right after I was 80% after levoquin)

Only the past 4month I have been on antibiotics (doxy,levaquin , ceftin) the levaquin I took for a month got me to about 80% but had to stop as it was killing my body .

I must add I have been on Bactrim before al this on and off for a few years for acne.

I know in my heart it is some bacterial because of the circumstances and how antibiotics respond even it's a little. I don't understand how every test is negative!. No doctor has mentioned bacteria such as ngu or those less often bacterial that are not in the common stds. My belief is that maybe because I took bactrim for so long and because the first two uro didn't do ANYTHING for 7 month this "infection" is a monster that no one knows how to find.

This last uro told me he can contact a infectious

disease specialist and do antibiotics through iv.

This has destroyed me inside and outside mentally physically emotionally spiritually I may have become insane aswell .

How can I have tested negative repeadtly for everything yet this started ONLY after the sex. Why do I respond to antibiotics if there is no infection. What am I supposed to do I cannot fathom a life with this pain this ed problems and knowing what caused this how am I supposed to have sex with a future wife let alone might. It be able to have kids !. I will be trying herbal after this and if not I will look into direct injections of antibiotics to prostrate. My fear is that There is a hidden disease that is slowly killing my ability to have kids and if I get married I will infect her and not be able to have kids. This is a bit of a rant but plz if you have any advice ( after semen culture the doctor mumbled something like there was a break mentioning something about the timing)(maybe my semen was not good?maybe it's already damaged?)
I have spent a lot of money on uro and I feel like everyone does the same basic tests. Who do I go to to order expensive tests that won't just check for simple stds, I want to be checked for different strains or ngu .....I just want my life back please try to help
