As a non-LD woman, here's what I glean from your statements. NOP did not force you to have "teeth gritting sex." You made that decision yourself and got through it with your own fortitude. NOP likewise had fortitude and was wise and strong enough to walk through that barren landscape to get you both where you needed to go.
I made that decision because at the time the alternative was eventually going to be no marriage.
Come on, we know HD is not going to "force" his wife to have sex. He can however, force his wife to choose between dealing with their sex problems or dealing with the demise of their marriage.
