I really think you are on to something in the last set of posts. Sorry if I have been in lurkage but I have been following. The thing that got me was when you mentioned that your H assumes that if you are tired, busy, or stressed that you (like him) would want to postpone. My H assumes the same. The truth is that I would postpone for that reason maybe one time out of ten. I realized that I will sometimes say, "H too bad it's late cause I'm horny." The reality is that I say that mainly to "feel him out". How silly of me. Bad mistake. I gotta work on just going with the "H I'm horny. Interested?"
Anyway, back to your H. I think that when he puts off ML although physically horny he doesn't do it to deny himself but more like, to preserve his energy for "more important" stuff. He mentions it or otherwise lets you know to show his "desire" for you. Does that make sense?
