<s>[INST] "I had unprotected oral sex just over a week ago. After 3 days I had a yellow discharge from my penis. I went to the walk in clinic that day. They gave me a shot and medicine for gonorreha & chlamyda. They also tested me for both and the test came back negative. The yellow discharge went away soon after the meds. It's been over a week and when I get an erection I have a clear muscus discharge, but not when flaccid. It does not hurt when I urinate, but I have discomfort what feels like in my urethra when just sitting around. It's not constant, it just comes and goes. What could this be? I am still worried about an STD, should I be worried?" [/INST] Hi. This looks to be just urethritis and may not be due to STD, but due to exposure to the oral bacteria of that partner.You must take antibiotics for 7 to 14 days to have a complete cure. You can go for the test of culture sensitivity tests of the urine and the discharge separately.Drink plenty of oral fluids to flush out the infection.Do not worry. And  learn a lesson of protected sex next time. </s>
