usually, I get these when I'm at work or lifting sth heavy I also felt a sharp pain for a sec between my testicles n anal area couple of times, I also experienced the pain after masturbating which sometimes I don't ejaculate.I gave blood test n urine test as well as ultrasound a couple months ago for my testicles n Dr said my tests were fine. one thing that concerns me is I received oral from a stranger about a year ago for like 30 sec can that be related to this like i received sth?shouldn't that be found on my blood n urine tests? I'm also virgin if you don't count receiving oral as losing virginity.
