Good articles. You are dead on about the counseling. Our C steered us away from that topic. At first I thought she was being strategic then she mentioned that she and her H had an average to below average SL. Then she left him for another man. Looks like sex was in there as a factor (not the only) somewhere.
On a related note, during discussions H has actually tried to deter the conversation in the following way: Oh, you aren't really talking about sex, you are talking about intimacy. The answer was yes and no. I was, in fact, talking about sex (not just intercourse) and I was talking about it as a form of intimacy. It was a long time ago and that whole approach sort of derailed me. It wouldn't now.
Maybe it is time to bring up the scheduel thing again.
