This hits the nail on the head. I'll admit, there are plenty of times when I engage sex with my husband not because I want it, but because it's my obligation as his wife. I realize that men are very sensitive to sex and not having it can profoundly affect them psychologically. I've told myself that once a week is mandatory. Twice is preferable, but when you have children it gets very difficult. There's a section in the Quran that speaks on this and encourages women to nurture their husbands and be kind to them. Sex is a man's weakness.
I need to be more cognizant of this and make it a priority to "nurture my husband" as well.

Fair enough, and props to you for doing what you feel you need to do to maintain things. But for some dudes, this kind of mindset could raise a problem. I don't know if I'd want a woman where half/most the time she tossed it at me was because she felt obligated or under marital pressure or whatever. Every now and then, I get, but at a certain point it stops being about the sex. It starts being about desire (I.E. Not "Do you want sex/dikk, but do you want ME"). If I couldn't keep my hands off my S/O, I'd want one who felt that same sort of craving for me, too.
