If you are considering an open relationship, or are a newbie at them, spare yourself some avoidable problems and buy this book. That said, it's not a book for everyone, because apart from the topic of open relationships, some of the anecdotes and scenarios can be too kinky for some.

The book is very well written by two women, both in open relationships, and the tone is close and easy to read. I think it's way more useful and informative than one of the other books about open relationships, "Opening up". Here you can find some useful insight as how to manage the difficulties that will almost certainly arise when you start a relationship of this kind. Also, you won't feel so alone when you read it, that all your conflicting feelings and thoughts are more than normal. The book has even some exercises for dealing with some of the most difficult feelings, like jealousy.

This is an updated edition of the one published some years ago, and it includes more info about polyamory (where the emphasis is more in feelings than just in sex, as other open relationships) and about singles. If you are wondering what singles have to do with open relationships, it has to do with the way you feel towards sex, weather you have partners or not. A slut is for the authors "any person of any gender who has the courage to lead life according to the radical proposition that sex is nice and pleasure is good for you".

For me, open relationships are more rewarding and closer to what most of us feel, but I also think that they are more difficult; at least in some ways, so the more you learn about them, the better. And the sooner. I just wish I had gotten a hold of this book a little earlier, because I think it would have helped to avoid some silly (and hurtful) mistakes.
