i experienced a discharge during a bowel movement about 10 months ago and went and got tested immediately. came back neg. for chlamydia, gonnorhea, and trich. ive started to notice that after i urinate i have more drops in my underwear than i used to and i heard that is a symptom. I also experience some occasional itching in my urethra but nothing consistent. Should i be retested or tested for mycoplasma ? or am i just paranoid
