Its obviously open to interpretation, there are biblical verses that say its not an option to deprive your spouse except by mutual consent. In a loving relationship we will do things for our spouse even if we do not derive a pleasure out of it. Obviously the reciprocation comes in another form.
I'm not a fan of the LD/HD dynamic where the LD is allowed to starve down the HD to nothing, and if HD attempts to negotiate or get LD to compromise upward it is viewed as selfish.
