I worried a bit when I first moved in with my now-husband but we soon became comfortable with each other and there was no need to be so hyper-aware of hygiene. That said, I shower every day (wash my hair once every three days)...but that's been my preference single or in a relationship.

Before we have sex, if it's towards the end of the day, I'll clean my self with warm water and body wash for sensitive skin (Cetaphil). I do this to wash away sweat from the day, not my natural odor. Washing your vuvla is a completely personal thing - some people are irritated by feminine washes and soaps, some are not. Some people prefer to use only water. Mine is fine with most gentle products.

As long as you are bathing regularly (every couple days) and cleaning your vulva with warm water or with warm water and a gentle wash when you do, you shouldn't have to worry about taste/odor. You can eat fruit if you like...there are mixed reviews on that...but vaginas are naturally musky in taste and smell. Can't clean that away.

I shave legs and vulva/bikini line once a week...armpits every other day (armpits just bug me).

If you feel clean living your every day life as you do now, you are perfectly clean enough to live with someone. He probably won't be showering twice a day and wiping himself! ;)
