(( VaginaPagina ))

Well, things that are generally good for you and your vagina are washing with just warm water and your fingers (no soap unless it's only on the outside - soap inside the labia can cause bacterial imbalances), wearing cotton underwear, drinking plenty of water, and eating a healthy diet with lots of fruits and veggies. But as others have said, you probably taste very good to anyone who is going down on you - they're there for sex, not for fruit salad, after all. ;) Seriously though, unless you have a vaginal infection or some other health problem, you most likely taste good.
