I'm in pool of pain, penis burning.

Burning pain in my penis started in 2019 June and i don't know why--------- 1. I have consulted plenty of urologists. according to them, I don't have urine infection. No kidney stone . I have done several tests , urine culture and USG and semen culture ..in semen culture bacteria shown as klebsiella pneumonia in scanty amount . for that I have consumed antibiotics for 3 months .. still pain exists . My doubt is I used to have habit of edging , ie , not ejaculating for hours .. continuosly watching porn or reading sex stories .. by rubbing my penis .. is that a causative of pain... I am aware what's edging and all due to the panic pain I start to search the causative , by that time I heard about edging ... is that a cause... I used to masturbate multiple times on that time and the way I masturbate was churning the penis between both of my hands. Is that way of sexual life causing this pain . help me im in hell of pain ...I'm surviving every day with pain ....sperm report is given below
