Tangy, fermented, or sour are perfectly healthy words to describe the vaginal odor created by a balanced bacterial flora.

Good bacteria help keep a vagina healthy by producing lactic acid, hydrogen peroxide, and other substances to keep harmful bacteria at bay. They help maintain vaginal pH levels by keeping it on the acidic side – between 3.8 and 4.5 for non-menopausal women and between 4.5 and 6 for those in menopause – to ward off the overgrowth of yeast and other harmful bacteria.

A metallic vaginal odor could be due to blood from menstruation or light bleeding after sex traveling through your vaginal canal. Blood contains iron, which explains the smell of metal.

A Bittersweet odor that comes off smelling a little like tangy gingerbread may be a normal bacteria in a bit of flux, affecting your pH balance and, therefore your aroma.

A bleachy or chemical vaginal odor could be attributed to a bit of urine in your underwear or around your vulva.
