This is just the thoughts of one person's mind, but it still seems to me Karen is best off discussing "physical desire" with her H rather than "sex". It's more authentic. If she was wanting sex with her H she'd be initiating and she'd be having it.
It's also fairly easy to imagine an LD spouse blowing off the HD spouse's sexual initiation and stated desire for more sex with the notion that "she's just horny, she'll get over it." The need to feel physical desire from one's spouse, however, is not so easy to dismiss. Especially, I would think, from a man who appears to sincerely love his W the way Karen's H does.
"I need you to initiate sex once a week" could be easily countered with an internal, "Hey, there are a lot of things I need, too. We don't always get what we want." Otoh, "I need to feel that my husband physically desires me"...can anybody really say, "That's understandable but it's just too bad" in response to that?
Maybe they can. Seems pretty harsh, though.
