STD?: White discharge with urination, particularly morning urination suggests an STD, specifically gonorrhea and/or chlamydia. You need urgent evaluation by your primary care physician to get STD testing and treatment. Avoid sexual activity until then and inform recent sexual partners that they may have been exposed to an STD. Always use a condom to prevent getting an STD during sexual activity.
