Query: A Mistaken Purchase

Skimming too quickly over the Amazon review of "Still Doing It" was a mistake. Careful consideration would have revealed clues to the book's contents. The book is edited by the proprieter of a "sex toy" business. Several of the stories are obvious endorsements of her business and the products she sells. All appear to be written or heavily edited by the same person. Nothing wrong with men and women enjoying love and sex into their late years. However the older people I know are able to talk about it in grown up language instead of four letter words. I consider the book porn and trashed it as soon as I knew what it was. "The New Love and Sex After 60" is a much better and more helpful book.
