I had considered the comparison, and what it would do to one's psyche to know that their partner had pursued in counseling a way to limit their investment in sex, and would be timing it and walking away at 15 minutes. I can imagine it would make one feel devalued and less than amorous, like it does for me to want to have any conversation with my H. I'd much rather go to Starbucks and chat up the person next to me. They actually seem to enjoy it. I'm sorry your W is like that. I don't know how to have an intimate R with someone that won't talk.
