One of the signs of good leadership is how you look out for those beneath you. That is, do you make sure that your subordinates are getting their needs met? If not, then you need to look into that.
My husband was in the Navy for a number of years and one of the things that I learned from him was, if you don't take care of the needs of your subs, then they won't be happy. Their moral will be affected in a negative way. Happy subs are those the hardest working subs, according to my husband. And that makes since.
In a Femdom relationship, he may sleep at the foot of your bed, possibly on the floor. But most FLR's are not like that. Odds are, he sleeps right along side your in your bed. (Notice I said, “your bed.” After all, you are the head of the house. If you wanted him to, you could make him sleep in a separate bed, or even on the floor, at least on occasion.)
Food, shelter, and clothing. Those are the essentials. To most men, sex is also an essential need to sustain life. It isn't, but they think it is. So, if you want your sub to be reasonably happy, so that he will do all those chores you want done, to the best of his ability, then sex is necessary.
Kinky sex is most likely what he wants, but if you are not into that, then he may have to adjust his thinking. That's where fantasy comes in. Fantasy can help to fulfill all those kinky desires he has without you having to actually do them. So you need to know what turns him on. If you have been married for a number of years, chances are, you know some of his fantasies, or, at least, what kinds of things turn him on. Use that knowledge to keep him as satisfied as you can and he will be much happier and more productive.
