I think every marriage is an individual situation. And then it breaks down to each individual who has their own basic needs , wants , feelings , desires etc.....
So it’s very hard to say. You should know , after the amount of time that you have been with your partner, what he needs and what you need.
Of course men desire more sex than woman due to a built in mechanism to procreate. Then there’s just plain lust , addiction.
I think that this problem you describe should be brought to professionals. Like marriage counselors.
