After which I noticed some yellowish white discharge from my penis. Was this answer helpful? I find yellow stains in my boxers every morning. Chlamydia and gonorrhea can cause serious health problems when left untreated, including infertility, so it is important to get tested for any instance of penile discharge. The tests are negative for STD's and there is nothing found in the tube.
