I can’t handle my husband’s sexual demands

How do we solve this

I am having a somewhat big problem with sex in my marriage. For many years, my husband and I have fought over this because he always wants to have sex. He says he thinks about it and needs it often but for me it is not a big deal. I can go for weeks or months without even thinking about it.

He gets angry when I say I am too tired (often) and he is offended that I don’t seem to want it as much as he does. I feel like this is a battle that I just cannot win and I may have to give in to his demands even when I don’t feel like it. I think if I knew how often a man needs sex I could plan for that, and maybe that would help. Please advise me.
