I am 42 and having the best sex of my life with my wife married 16 years ago. The book The Enlightened Sex Manual [0] is a great ressource on that matter.
TL;DR of the book: ejaculate less often, be more awake during sex.
If I married a woman 15 years younger than me and then kept the interpersonal tension high it would probably be great sex when it happened. I don't care for the drama and the WTF 'gtfo' nights when you are involved at that level.
The whole ejaculate less and be more awake thing I can scarcely contemplate seriously. If all it comes down to is satisfying your partner while wide eyed and eager for 'great sex' you are sadly mistaken and won't convince anyone other than sad sacks looking for formula.
