Jane Juska was on several TV programs and Discovery Health Channel had other 65 to 75 year old women that liked sex.
The add was more daring than her actual experiences. Jane was selective and did meet several guys, some she went out with. Some she did not like so she dumped them.
Some guys she kind of liked but didn't have sex with. The guy she had the most sex with liked fine dining and books so she found someone compatible in many areas of her life. I did not read the book so don't have all the information.
I think LDW see her as very unusuall. At least BB did.
