Two weeks ago I had unprotected sex with a woman I met just that night. The sex lasted a couple of minutes and I did not ejaculate inside of her. I began freaking out that night and the next day and scheduled an apt to get some STD work done. Basically, I was told to wait a couple of weeks before actually getting any tests done. That was before I started noticing things in my body. Roughly 5 days after my encounter I was driving and I started to feel pressure on my bladder. Prior to the pressure I guess I would notice any kind of tingling or sensation inside my penis that I probably wouldn't notice before (urethral awareness?). Was it my mind playing tricks on me? Or is it something serious? Anyway, the pressure would come and go over the next few days. It doesn't burn or feel irritated when I urinate either. It's like urinating is my only way of relief. I limited my caffeine and alcohol intake and I was feeling fine for the next few days. Fast forward to thursday (3/10) and the pressure started again. I drank a lot of cranberry juice and urinated a lot, but still no burning.The next day I drove another 3 hours and again, the pressure was there. But the moment I got out of my car and urinated, the pressure was gone, but only to come back again a while later. I ended up having an apt on the 12th and they tested for chlamydia and gonorrhea. They even took a swab of my urethra but the Dr. said there was nothing unusual. I'm honestly freaking out because I just want to know what, if anything, it is. I'm going to call an urologist tomorrow morning for an apt as well because the Dr. told me the pressure on the bladder is strange. But basically I feel pressure on my bladder that is greatly emphasized when I sit for long durations. I have NO burning or irritation when I urinate. There are times when I do notice something feeling weird in my urethra/down there, but again this is emphasized when sitting. Thoughts?
