Woke up sat morning and it burned when I urinated. Didn't freak out because I had only been with one person. It persisted for two days and went away when I dranked some cranberry juice. I went to the clinic to be safe and Dr. wanted to stick a small q-tip inside my litle man. I declined and asked the Dr. if they could determine by looking at urine. She examined the urine and said there was evidence of a little pus. The Dr. then said that it didn't look like a disease. She prescribed Doxcycl and called it a day. Is it a chance that I have a STD
