"That is, it is more virtuous to be celibate when your spouse does not consent to it than it is to have sex when your spouse does not consent to. Somehow seems to be a reflection of American puritanism."
Um no. It's called marriage. It has nothing to do with "American puritanism". Usually when you are in a marriage (in the majority of cultures) you stick with that one person. In the Middle East you could even get stoned to death for it. It's not an American thing. Some go into open marriages which is a choice.
Bottom line is that if sex isn't a big thing for one spouse, it is up to the other to determine if they can live with it or not. It's an individual choice.
