You know your wife better than anyone here so do the things she likes and that make her feel special then spice things up. Maybe cook her favourite meal in something that will make her eyes pop and her mind race. For my wife its all about keeping things warm. She hates the cold, so i will heat the bed up with hot water bottles, close the door to keep the heat in and light a yankee candle. Then its massage time and it's all about the sexy times. Slow teasing with toys, before things get really naughty.
