My prostate is boggy, and my semen culture showed E.coli bacteria. What to do?

Hello doctor,

I am a 27 years old, and I have been suffering from pain during ejaculation. After ejaculation, I feel severe burning during urination at the tip of the penis, from the past six years. From the past year, at the time of ejaculation, the semen does not come out with force, and it remains in the urethra. When I urinate after intercourse, then semen comes out with urine. I started having erectile dysfunction also. The semen culture analysis showed E.coli bacteria. Since then I consulted many urologists and tried all possible antibiotics, but I only had temporary relief. Every time there was an E.coli infection, all the symptoms come back. After a physical examination, my urologist told me that I have grade 1 prostate boggy because my prostate was hurting when he was palpating. I have lost all hope, and I am depressed. I want to know about intraprostatic injection because it is the only thing that can cure me. The ultrasound and uroflowmetry are normal. Please help.
