Wow this should be interesting to read comments but I bathe twice a day. Once in the morning and before bed, I personally couldn't imagine going to bed unshowered.
The thought of sleeping on dead skin cells in my bed grosses me out. :/

But I've never done anything special before sex unless we are planning to do oral then we shower together before. Your vagina self cleans itself so no need to cover it up with feminine wipes.
