pains in my urinary tract and colorectal areas got worse

Hi I'm a 22 year old male and new to this place. I've spent a long time embarassed about the pain I've been feeling and I have been struggling to afford medical bills to persue it more at a hospital level. I've been having pains in my urinary tract and colorectal areas that have gotten worse over time.

I'll start with a list and explain what it's like.
1. Prostate: burning pressure pain, makes me feel like I have to urinate when I don't at times, usually gets much more intense after ejaculation, end up stuck in the bathroom for up to a few hours.
2. Urethra, burning pain itch around the the mid section of the penis, usually get smuch more intense after ejaculation, ties into 1.
3. not sure the title but just behind the foreskin on the bottom side of the penis is always very very sore inside and I have to watch how much pressure I apply there because it will sting like hell if I push too hard, also that gets much much more painful after/durring ejaculation.
4. my bladder is usually very sore aswell.
5. kidney pain, occasional sharp pains.

now for the i'm not sure entirely about how to explain. I'm mentioning these problems in this same post because both urinary tract and colorectal problems I have seem to agrovate one another.
1. constant pain in colon area, difficult to perform bowel movements, very painful durring and after bowel movements, causes quite a deal of pain to urinary tract, sometimes makes the urgency occure.
2. pain and itch in anus, almost an all day thing.
3. yellow discharge from anus, that ones recent to this year.

this has been ongoing on for some years now, my parents were very neglecting and didn't feel it was worth paying money to look at it. I'm hoping someone out there can please help me find the answers, I did get ecoli last year from bad food that was "successefully treated" not sure if that has anything to do with this becomming worse or not. I've seen doctors many times and always gotten generic responses that never work, the last time I saw a doctor a few weeks ago they saw there was infection in my urine and gave me antibiotics, they didn't do anything. also if people are thinking I have std's I don't, thats something i've had checked multiple times and I'm in a committed relationship. If anyone can help shed some light on this problem please share your knowlege, durring this last year the pain has increased much much worse and i'm struggling to be able to even function properly, I'm kind of at my whits end as for where to go from here.
