I have exactly the same issue. I'm slightly strong-smelling (probably because I drink coffee) but not icky. It's just that the boy I live with has an extremely sensitive nose. I don't use "feminine wash" -- it's no better than gentle soap (sometimes worse, if it's scented) but soap's not good for my vulva either. And "feminine wash" is usually more expensive than soap.

Two things that I've found work best for me and the boy I live with are having oral sex fresh out of the shower, the moment I'm out and drying off, or using a tiny bit of very neutral-tasting lube on my vulva. It sort of dilutes it. At any rate, given his nose, I wouldn't expect him to go down on me if I'm more than an hour out of the shower.

(One reason I know my pussy's fine, just a little strong, is that my other boyfriend says that's the case.)
