The "wall' is a total myth. Life experience, how you live and treat your body dictate when the "wall" supposedly happens. To me the life experience only adds to the sensuality and beauty of women. I've know women who were 70 that because of how they lived were more attractive than a woman of 24 because she hasn't lived.
For me its the affirmation that as I age, I can still be found attractive, the attention they give and the willingness to give up control to me, oh and did I forget that eagerness to please. The obvious is the skin and body, but I've met many "older" women out there that have be as exciting or more exciting than any younger woman.
Guess it's confession time, yes with a married co worker, and several times with single and married mom's on teams I've coached. Even a few clients from time to time.
