I had protected intercourse but received unprotected oral from female. About two or three days later, I had what sounded like gonorrhea symptoms like feeling I have to urinate and had some greenish brown stains in my underwear for a few days in a row when I would wake up. I never saw anything come out of my penis tip but the stains would be there from the night. I had two tests on urine for gonorrhea and chlamydia but both were negative. Is there anything else this sounds like? Thanks
