I am a married male. About 2 weeks ago I found my self at a gay establishment where I recieved oral from two other men and returned favor to one of them. No explanation for my stupid behavoir. About a week after incident I noticed soreness in right testicle. On the 10th day after episode I was tested for STD panel. A day or so after that on one instance I noticed bloody spotting in underware and what appeared to be blood in tip of penis. Still have sore testicle. Today I found out that results were negative. Questions: Did I go for testing to early? Lab said that among other things they were testing for Gonorreah and Chlamydia. Would NGU show up in those tests? Should I be concerned?
