What std can cause a watery white or yellow discharge?

The most common STD that can cause a watery white or yellow discharge is gonorrhoea. This is a sexually transmitted infection that is caused by the bacterium _Neisseria gonorrhoeae_. It is spread through unprotected sex, including vaginal, anal, and oral sex. Symptoms of gonorrhoea can include a watery white or yellow discharge from the penis or vagina, pain or burning during urination, and pain in the lower abdomen. Gonorrhoea can also cause complications, such as pelvic inflammatory disease (PID), which can lead to infertility and ectopic pregnancy. It is important to seek treatment for gonorrhoea as soon as possible to avoid these complications.
