There are 2 reasons why I find this book extremely helpful with exploring my own sexuality - it is easy to read and brutally honest. It doesn't assume you have a medical degree (everything is explained in layman's terms) and both the potential positives and negatives are thoroughly discussed.
'Ultimate guide to anal sex' gives a great grouding in basic anal anatomy, health, and the need to explore this area on your own before including a partner. After reading this book you will not suddenly find yourself an experienced player capable of 'anything', but it will give you honest information that will lay a wonderful groundwork to explore anal pleasure on your own and with a partner.
It is by no means an 'advertisement' for anal sex (even though it's obvious that the author is very experienced in this area), indeed you might read this book and say 'it's not for me'. But it will go a long way to answering your questions that are difficult to ask and make you better informed as to your own choices. If you still have questions after reading this book, the last chapter contains a considerable listing of resources that will put you in contact with other information.
Isn't it wonderful that we live in a world where books can be published that gives us insights into one of the most taboo sexual practices???? Even if you think you are 'experienced' and need no instruction, read this book. You might just find you do indeed learn something new. After all, isn't that what sex is??? A constant exploration of ourselves and each other??
If you're more expereinced or lookig for something in more detail, then go elsewhere, otherwise, I recommend checking this out. I would have loved to have had a copy growing up in a small, sexually repressed New Jersey town (Haddonfield). A lot of the stuff described in the book Ryan Solot and I had to discover on our own and I think that played a big part of our relationship.
Regardless, it's worth the read. Some of the stuff may surprise even the "very knowlegdeable."
