Question: Back in 2015 I had unprotected heterosexual intercourse. Less than a month later, I got really bad pain in my left testicle and lower left abdomen. My symptoms started with my stomach rumbling a lot if I remember well. I went and got testing and I was negative for ghonorrhea, syphillis, chlamydia, and hiv. There was some blood found in my urine but it was invisible to the naked eye. The next time I was tested, there was no blood found and the urine was normal. I also had a ultrasound of the scrotum done, and it was normal as well (slight skin thickening on the left side, but not doctor wasn’t sure of the significance). Since then, I have always had a slight yellowish mix in my semen. My left testicle has also been super sensitive during any sexual activity. I am searching for answers and I have not got an explanation yet. Would you have and idea? Thanks
