If you are old enough and (consider yourself a female) you can be a Crone or a revered elder.
I kinda like the idea of Crone because it sounds like somebody you should respect and not mess with if you don't want to be hurt. Age does bring advantages.
The site explores the dimensions of Cronehood. Essays, cross-cultural explorations into other societies and menopause information - http://www.yoni.com/crone.shtml
Now you may be plowing up the north forty but I leave you with an inspirational tidbit about Grey Panther founder Maggie Kuhn. She was in her 80's and continued to have sex with men who were in their late 20's to 30's.
I say never give up hope and look to the elders for inspiration and guidance.
