she expects me to initiate and she will accommodate my need for intercourse. She doesn’t need it nor does she ever think about it.
I will submit your "problem" is maybe solved, if she is indeed serious. If you will read the scientific paper
@Laurentium linked to in another thread, you will see this is in fact the defacto norm for a woman who has been married a long time. Look up "The Female Sexual Response: A Different Model" There is a diagram that will explain how it works. Responsive Desire is the norm and maybe the only game in town with a lot of females. They don't start out aroused, but will become aroused with some effort by their partner Look at the diagrams in the paper.
Women married to the same old guy for years don't crave sex like a man does. In fact, after the first year or two and especially after kids arrive, sex is nearly the last thing in their mind. So if a man approaches them directly like they did when dating, it isn't going to lead to good things. That is just how it is. If you review the diagram you will see how the whole scenario works.
I will say my wife does need and obviously thinks about sex. But not to the extent that I do. If I didn't initiate, she would think I had lost interest in her, and THAT would be a problem. She just isn't going to initiate, it has never been her nature. Even when we were dating. Maybe it was her upbringing, that girls aren't supposed to start the romancing. Who knows? And really who cares? I surely don't! We have had a wonderfully full intimacy for a very long time. I get her motor started in small ways. Some conversation, a caress here, a kiss there, a whisper in her ear, some more conversation. Romance. Spend some time. She very readily and enthusiastically responds to me romancing her. What is kinda funny is she of course after all of these years knows where we are
probably heading, but still plays the game.
