I am a male and I am 21 yrs old. I had unprotected sex for about 30-45 seconds 4 weeks on Feb. 22. I was tested for Chlamydia and Gonorrhea, which came up negative. I was fine for about seventeen days after my exposure. (Before Feb 22 I had sex only once and we were both virgins). Then the tip of my penis felt colder for a couple of days and it felt like I was leaking after urinating. It was in small amounts(drips), but enough to irritate the tip of my penis and irritate my penis while walking as it brush up against my clothes. It was not severe chaffing, only mild. I do not have any reasons why this could happen. Could it be psychological because I thought I had some kind std. This problem has been ongoing for 9 or 10 days. I even went to an std clinic to see if there was anything wrong visually with my penis and the doctor said it looked fine. What is going on?
