Husband has no sex drive?

My husband has barley any sex drive, we have sex maybe one a week, usually once every two weeks. I don’t know if it’s his sex drive or if it’s just me he doesn’t like to be with. I never shame him or pressure him or make him feel badly about not wanting to have sex because that’s his decision always. But i just want to know if there’s something i could do to help. We are 21 & 22. I have a very high sex drive. What can i do to help make our sex lifes better for both of us? Is this normal for a 22 year old male?
