The "easy" cure is to get a suppository from the pharmacy, and then cut out all the Sugar and any coffee from your diet, and eat a pineapple every couple of days.
It won't cure it right away, as the "odor" problem in your vagina is a symptom of a problem in your intestines. So even temporarily curing the odor will not stop it from returning.
Pineapple and grapefruit are well known to improve the "taste" of women and men. Taste is a function of smell.
