If he feels like you are depriving him, then you are. I think we have all been there at some point in marriage, for the most part, men want it, and once we have little kids, we don't. Take it from an older lady, who has been there, done that, and don't tell him that he is getting enough, try your hardest to give him what he wants, he wants you because he loves you and it could not be anymore simple than that. It does not matter if we like how they feel about things, telling them to get used to living life the way we think is not going to change the way he feels one little bit. Sex, and sandwhiches. If you are not having sex with him, make him a sandwhich. Soon, if he is getting it as much as he likes, you will see that your work load is less, he is happy, and he would do anything for you because he feels so loved. Men feel love through sex, ask him if this is true. He will never get used to thinking like a woman, he just won't. I can tell you, that since I did this, my life has never been better. The more sex you have, the more sex you want to have, and you are the only naked woman in the room, and he wants you to want him as much as he wants you. Secret of life.
Now that he knows he will have as much as makes him happy, it is never an issue if we go longer than a few days. Makes them feel loved, and secure. You will never know what you are missing if you don't give it a try, but I can tell you that you will get more of the same guilt trip if you don't.
You are totally normal, but so is he. Men are different than we are, and you will get everything you every wanted by making him happy. Really.
Much happiness ahead for you, I hope!
