I found this book to be helpful and handy now that I’m well over forty and finding that balance between quantity vs. quality. Sex After Forty by Calvin Colanussso does a really good job in helping us all to understand some basic functions and realistic expectations of the “middle years” and how to make the best of them.
The book is short and concise, so it’ll also serve as a great reference book from time to time.
Enjoy, and enjoy better than ever!
