Query: Not the greatest guide

I was very disappointed in this book. My longterm boyfriend and I were looking for new and interesting ideas to liven up our sex life. This book seems to be more geared for first timers or the very timid. Also, the pictures weren't explicit at all and the positions were very self explanatory so its almost as if the pictures are not needed, like in a health book with too many official names and explanations of what each part does. My opinion would be, don't waste your money unless you are looking for a cheap health lesson.
