I go see my doctor and ask for a full STD
screening, which included a first catch
urine test for chlamydia and gonorrhoea.
I follow the instructions carefully and make sure not to urinate two hours prior to the test, but now I am questioning if I did something that could alter the results. Right before urinating, I noticed some lint on the top of my penis. I used my boxers to dab it off, and then urinated into the first cup.
