This is typical duty/mercy sex talk. He obviously is not into the whole sex thing. My wife also says similar things BEFORE sex. I will do all kinds of foreplay on her, even give her an orgasam orally. Then she finally is willing to have sex. She will roll over and say somethin stupid like, "OK, let's take care of you"! All of these expressions are just HUGE indicators of people that are only going through the motions, they have no desire for sex. It really makes the HD spouse wonder if any of this is even worth it.
