Cook him his favourite dish, best can be a steak.
Dress sexy or dress accordingly to his fantasy, like a student or a nurse or even a police woman,etc. if don't know, find out from him

Be passionate and tell him U appreciate what he has done for U n you are proud of him being ur man

For a start whisper to him in a sexy voice or tone to spice things up

If U both got kids at home, put ur kids at ur parents or in law's house for a night
Make a good quality private couple time for U n for him
