That quote comes from Mojo although it is also true in my M. I will get laid periodically when all the planets align for my H. What I won't get is regular sex or spur of the moment sex. He won't suddenly come do me in the bathroom or my clothes closet or in his basement office. He won't make a lewd compliment when we are dressed for a party. He won't give me an open mouthed kiss at the end of a workday, feel me up and promise something more later. He only seems to "want" me when it is convenient for him. Never mind what my desires might be.
I am in a resentful mode and I realize that I do have it somewhat better than others. However, I often wonder if we will soon move from the current lack of frequency (once or twice/month) to an even worse frequency. I have no reason to believe that it won't happen that way.
Michele's book might be helpful if my H ever read it OR would define the problem in a similar way to how I do OR would be willing to consider my viewpoint even if he disagreed OR indeed, if he truly valued me (which I often doubt).
