Mike, This is just a guess but I'd have to say that it is your desire for her, and not the actual initiation which makes her feel sexy and womanly.
So even if you back off, she still knows that you want her and so she feels desirable.
I will say this, though: I don't think that simply because a woman has a man wanting sex with her several times a day that she automatically feels sexy. I even think that it could cause the opposite feelings...and she could feel like a fraud or, worse, turn it into a reason to lose respect for the man. Kindof a "What is wrong with him that he wants a frigid acting woman?" type thing..
I will say that I STILL believe that an LD woman has a better self image than an HD woman because most of the LD women that I know in person (not pointing a finger at anyone from the bb) would lay down and die if they got rejected once, let alone repeatedly.
But I don't think that the fact that they are pursued for sex = high self esteem necessarily.
Mike, I think if what you are looking for is your wife to be motivated to fix your sex life because she feels like less of a woman, then you will have to remove your desire from the picture completely--in essence, become LD yourself.
I can hear you laughing all the way in the midwest.
