Vaginal discharge and secretions are a normal, healthy part of your reproductive system. The vagina -- which is not the whole of your genitals, that's called the vulva, but the flexible tube behind the vaginal opening and inside the body -- is a passageway between the outside of the body and the internal reproductive system. The pH balance of the vagina is acidic, with "good" bacteria, by design, which helps keep infections away. Vaginal secretions are how the vagina cleanses and regulates itself -- how amazing is that? -- in the same sort of way that saliva helps keep your mouth clean and healthy.
