Well, If I'm honest, I will have to say that I just wanted sex, not necessarily with my H. I knew that our SL was so strained that neither one of us used the sex as a way to build intimacy or have some sexual fulfillment. In fact, it created more tension in our M, so why turn to each other that way, you know?
It was a vicious cycle. But my HD was still in full effect in general, that was the problem. Still is I guess.
I certainly don't think the "heat" starts with a woman. It has to be a two-way street, at least it does for me.
Not sure if that was what you were asking but...
