Senior FLR's?

Can't help but wonder how many senior couples actually have a female led relationship, (FLR). There are a few blogs on the topic that are reasonably well written (better than this one, but that isn't too hard).

There is a logic to it happening. The empty nest brings relationship strains that were easier to sweep under the rug or work around when there were kids to care for and transport are brought out into the open, and it brings freedom to work out your own solutions.

For some people (I have no idea how many) that seems to be for the partner with the more natural focus on relationships to just take it over, to be the officer-in-charge of the interactions between the two.

And, for some guys (again, how many I have no idea) there is a sexual turn-on in being subordinate to a woman. So far, a win-win, but don't forget the male's greater tendency toward fetish. How far into the "side-show", "comic book-like" world of femdom are most women likely to be willing to go, even in the context of building a better relationship? (Again, I have no idea.)

Interesting idea? There is a general discussion of power in relationships here.
