I decided to research this topic from a psychological perspective and started exploring books that are still available to read (many go out of print quickly). This 245 page paperback by a married woman in the "lifestyle" with her husband for a while now was the best book that I found. Let me say that this book is not just for beginners -- there is something here for all who choose to investigate swinging. The book covers pretty much all aspects/questions concerning swinging. While it is not a scientific study, it is one person's opinions and personal accounts and they appear genuine and accurate. The author looks at roughly 75 or so areas directly related to swinging, covering pretty much all of the bases, including: who are swingers?, single men/women in swinging, jealousy, costs involved, clubs and parties, precautions, suitability for the lifestyle, etc., etc. She cites what she describes as the three rules of swinging: 1."Swinging is what you make it. Swinging is about letting go of outdated notions about sex and relationships. It's about giving up hang-ups and allowing yourself to be completely free while allowing your lover to do the same. 2. You must go into swinging for the right reasons. And those reasons include wanting to get closer to your lover and to get in touch with who you really are and the sexual being inside of you. 3. Swinging is a very private thing between you and your partner and not between you and the rest of the world."
The "personal and related experiences" used throughout the book are very enlightening and add to the flow and readability of the book. Obviously, this is not a book for everyone. However, if you, alone or with a partner, are considering the swinging lifestyle, this is an excellent book to get your hands on and read.
I think that for a relatively small paperback it is a bit overpriced ($16.95 US) yet there are so few books like it that it is worth the price if you are truly serious about this topic. On the other hand, look for a used copy as you may well find one around. I might also note that some of the typographical and grammatical errors are annoying but don't detract from the message that the book seeks to deliver. The book is indeed "upfront and honest" and a quick read. Note: I read "Considering Swinging" by Ed and Dana Allen before this book. That is a 53 page booklet which is not nearly as good/helpful as this book, in my opinion.
Ms. Bellemeade has done an admiral job of introducing the swinging lifestyle to beginners. Check it out if you are inquisitive about this topic...
