I just wanted to reiterate that putting scented stuff in and around your vagina is usually bad, but especially "feminine washes" or douches. It can upset the natural balance of bacteria and things in your vagina and cause infections. That said, the best way to keep clean - warm water and your fingers, in the shower, maybe with some mild soap *only on the outside* (your vulva) if you feel you need it. I second the recommendation of unscented baby wipes sometimes when you feel like you want to clean up a bit.

Foods that might make you more strong smelling include meat, coffee, asparagus, brussel sprouts, and sometimes spicy food. Pineapple is supposed to help sweeten your taste. Mostly though, just make sure you're hydrated, eating right, and letting your vulva breathe. If you're doing those things and you don't have an infection, then there's nothing wrong iwth your smell - it's probably your boyfriend's sensitivity, not your scent that's the problem.

I'm sorry your mom wasn't very helpful with the whole growing-up-and-keeping-you-informed thing, but if you hang out here for a while you will learn a lot of things your mom never told you really quickly, I bet. :)
