Received this yesterday - it is a pretty big book, not in terms of the number of pages, just big! It has a clear layout with big text and chunks of information that are easy to read, and there are lovely sets of photos on every page. The spine is easily damaged by the size and weight of the pages but the content is definitely worth it. Dotted around the book are 2 page spreads covering different positions, and there is a 4-page spread on 50 sexy suggestions - these little ideas and positions are inspiring if you're skimming and don't have time to read whole chapters - or the patience, like I didn't yesterday! I've already tried out two suggestions and 1 new position, this book is so inspiring and broke through a bit of a dry spell my partner and I have been having, we were amazed! Most of the positions are standard ones but the suggestions vary widely. The chapters themselves are detailed and suitable to read aloud to each other, and the little quizzes are great for going over with your partner, I actually learned a couple of things about mine. So far I love this book and cannot wait to finish reading it with my man =) definitely worth buying!
