This is the very first book I ever read on bisexuality. Since then I've found better books on the subject, but this is still a book I'll put my nose into again. The reason it's not the "best" is because I didn't relate to most of the bisexuals Klein interviewed. It was kind of a downer, some of the uptite bis in this book. Then again, he didn't interview very many people. Especially compared to "Bi Any Other Name: Bisexual People Speak Out". Now that is a book where I related to many more of the people. Just goes to show we (bis) are all different. I will always have a lot of respect for Fritz Klein and found his scale on bisexuality very good. Although I don't agree who we prefer to socialize with has anything to do with orientation. I could enjoy a cup of coffee with anyone, that says zilch about orientation! Other than that, I liked the scale. This is an interesting read, for the most part.
