I have had a slight itch or irritation in my urethra that has come and gone for about 12 weeks now after a brief unprotected sexual encounter. It will be mildly noticeable for a day or two then gone for a day or two and then return etc. etc. No irritation during urination except when my urine is dark from dehydration, but nothing too noticeable. I have also noticed thin milky white discharge immediately preceding ejaculation. Which I don’t remember encountering prior to this last month. I have also had a slight rash and irritation in the crease between my thigh and genitals. No lesions or raised bumps just a slight redness. It stings more than it is itchy but also is quite mild and irritation comes and goes though the redness lingers. This has occurred twice in the last 3 weeks both have occurred after sweating heavily. The first time it cleared up after a few days maybe a week. I was using antifungal shampoo to help it along. I have tested negative twice for all STIs on a ten panel test (hiv 1, hiv2, hsv 1, hsv 2, syphilis, gonorrhea, chlamydia, hepatitis a, b, c,) and also negative for trichomoniasis. These test were conducted 4 weeks and 9 weeks after exposure. I was also tested for a urinary track infection at 5 weeks which can back all clear. Any suggestions what this could be?
