Husband wants sex constantly

Me and my husband have been together nearly ten years and he still has a crazy sex drive even now. We are married with two kids and I love him to bits and still find him attractive but to be honest I just have no interest in sex anymore. I’m so tired and it’s the last thing I want to do. I love being that close to him but would happily just cuddle instead. But he always hints at it on a daily basis and makes jokes about whether we’ll have it tonight or not. We still do it once or twice a week so it’s not like we never have it. Anyone in the same boat with any advice? I don’t want him feeling left out or unattractive but it’s driving me crazy.
