On a night when nothing is planned, get a bunch of rose petals, and spread them along the floor leading to the bathroom. Have the lights off in the whole house and use candles along the way to the bathroom. Prepare a bublle bath for her, and have a neglege sitting on the sink counter, next to some perfume that you like and the blush. foundation, and lipstick that she uses. While she is in the bathroom, cleanup the petals that lead from the door to the bathroom, and use them to lead from the bathroom to the bedroom. In the bedroom prepare a dinner of what she likes to eat and some champaigne. Have rose petals all over the floor and the bed. You could use silk sheets on the bed. And let things happen from there.
