In my opinion, this is looking at the whole thing backwards. If a person is simply not in the mood, perhaps he is watching MNF, and his spouse in her typical way tries to initiate intimacy, the proper reaction is to give oneself lovingly to the wife. She may know he really wants to watch MNF, but he responds in such a way that it is not a major turn off. And lets face it, once the action starts, the “not in the mood” feeling often disappears rather quickly.
I bet you every married person on this thread has had to do a little “seduction” at times with their spouse to get things moving. What is wrong with that? Its not a turn off, its often quite the opposite.
