I had an encounter with an escort about 14 days ago. She briefly performed oral sex on me, probably less than a minute and finished with a hand job. About 5 days ago I noticed some discomfort in my urethra. Not really pain when urinating but some frequent urgency. The slight buring sensation somewhat comes and goes. 1 day after the burning sensation began, I started to feel a lot of lower abdominal discomfort mostly in my lower intestinal area, loss of appetite, so headache and general malise. I have had absolutely no evidence of any type sore or lesions whatsoever not have I had any fever at all. My question is: Can I have these flu like syptoms from NGU and how worried should I be about herpes given that I have not had any sores at all? Thanks all for any advice you can give.
