I received unprotected oral sex from a sex worker a couple times back in May. I was tested for STD's i believe at least 3 weeks after the exposure and all results came back negative. However I was diagnosed with Molluscum in my genital area. Around maybe late June/early July I began having discomfort in my lower abdomen and it felt like there was a lot of pressure. I started taking Bactrim from my doctor and that sort of went away. Right after that I started having a stinging sensation off and on throughout the day towards the tip of my penis and would also feel it when I need to urinate & afterwards. Never had any discharge but after I urinate my penis does leak urine and I have to shake it out. Since then I've been tested for HIV, HSV 1 & 2 a couple times and they've all come back negative. I've been seeing a urologist for about a month now and he says it could possibly be Prostititus. I've taken maybe 3 or 4 weeks worth of Bactrim up until now. I've read online that Bactrim isn't the best medicine for those STD's. I just realized that I never did follow up testing for Chlamydia or Gonorrhea so went and did a urine test for those 2 STDs and I am waiting for my test results. I would like to know if my treatment with Bactrim would have cleared up those STDs if they were present or if I could potentially have one of them.
