Why does my breast and vagina taste like onion when i'm sexually aroused ?

Onion vagina: You have apocrine glands, both in your breast and in your perineal area that ptoduce fatty secretions when you are aroused and the bacteria on your skin break down those secretions and produce the onion odor. See your gyn and make sure you don't have anything else going on. Patients tell me that 50 mg of clorOxegen twice daily helps a lot.
