You hit it on the head here. THE ULTERIOR MOTIVE. Except I am the one with the ULTERIOR MOTIVE. I try to do more around the house, to help shoulder the burden so my wife is not so tired, and what happens. The wife thinks that I am trying to do more for that sneaky "ULTERIOR MOTIVE", to get sex. I try to make changes in me that will make me more attractive to her, and it always comes back to that sneaky "ULTERIOR MOTIVE" for her, I just want sex.
NO, the "ULTERIOR MOTIVE" is to have a FREAKIN' better marriage. It seems I can't win either way!!
