Mrs. K. has a valid complaint.
She's the caregiver for Mr. K..
"I take care of him all day long. He keeps me up a lot of nights hollering out in his sleep and getting up to pace around the house. I have no interest in being intimate with him but he wants to try and have sex almost every night."
Years ago I read an article by a sex therapist.
She noted that for many men, foreplay often consists of walking across the threshold to the bedroom. For many woman, foreplay consists of everything that has happened in the previous 24 hours.
This is a perfect example.
Things aren't looking too promising for Mr. K..
