Does the average woman's libido increase after menopause?

It is a part of life and it sounds like you are doing a great job of supporting her ...keep up the good work! You all sound like a great couple. Be glad for what you have -a woman who loves you so much -enough to try to continue to satisfy your appetite. She knows you are a "keeper" and you know she is too. You all seem to have a history together and it would probably benefit you both to just try to ride this out. Consider it as taking your relationship to the next level where you enjoy each other's company in other ways. Maybe think about the fact that "the shoe could end up on the other foot" and you develop and ED problem (God forbid!) but you would certainly want some understanding. Maybe she could look into some HRT (Hormone Replacement Therapy) or, seems like, I've heard of a female Viagra? Anyway, love each other and enjoy having someone to enjoy life's journey with.
