When you have vaginal odor it could be normal or it could be due to vaginosis.
Symptoms of bacterial vaginosis include an unusual vaginal discharge that has a strong fishy smell, particularly after sex, a change to the color and consistency of your discharge, such as becoming greyish-white and thin and watery.
To get rid of vaginal odor shower regularly and only use mild, unscented soap and warm water to clean your vulva.
Bathe and put on a clean outfit shortly after exercising so that you're not sitting for too long in hot, sweaty clothes or a damp swimsuit.
Warm and wet environments are ideal places for harmful bacteria growth.
