I think I may have POIS, but I have symptoms I don't ever seem to see online. after ejaculation, I experience severe to mild burning on the tip of my urethra, as well as burning sensation in what feels like my prostate area. I also generally feel sick to my stomach. these symptoms start about 15 minutes after ejaculating, and last at the most an hour, though sometimes I notice the stomach sensation the following morning. I have had my prostate checked and it was normal, and I have been tested for STDs but am clear there too. I have a lot of food allergies, and take thyroid medicine. I would say these symptoms happen 75% of the time. I do plan to see a urologist, but with how little the medical world seems to know about autoimmune diseases, I wonder what I'll end up getting out of it. still will see one though. thanks for reading!
