If you go into marriage thinking that you are meant to "perform" for her, and she for you, then you have the wrong idea.
Forget what our culture is saying about "sexual compatibility", your "sexual needs", the need for "sexual fulfillment". It's just a particularly pernicious form of consumerism; the media is making you want things you don't need (again). For thousands of years people have managed to live and reproduce successfully without worrying about these notions.
Just don't go there. Stay away from dating advice sites, the "manosphere", pick-up artists, and all that nonsense.
