I have had a thick yellow discharge and burning sensations after urination, for about 3 days. Today I went to the clinic, and they got me to urinate into a bottle. She said the results will come in 3 days or so. She gave me a penicillin dose of four pills anyway, since I had visible symptoms of either ghonnorea or chlamydia. My question is, if my symptoms do go away, when is it safe to become sexually active again ?
