There are a lot of sex guides out there, but I doubt any of them are as useful, informative, attractive, or easy to learn as this one. This guide really does spice up your love life.The cards are high-quality, printed on excellent stock and bound neatly in a heavy-duty, smooth cardboard box. The illustrations are tastefully sketched and do not distract from the attention given to the simple instructions on each card's flip side. Each card falls into four categories: woman on top, man on top, rear entry, and standing. Each entry is rated in difficulty from one to five, and the brief instructions contain a surprising wealth of information on each position: the benefits for the woman, the benefits for the man, contraindications (such as for a well-endowed man or for a man with a small penis), and possible variations. The deck comes with an excellent introduction complete with professional advice and suggestions for how to use the cards, when, where to leave them as hints, etc. The advice is effective and very thoughtful for couples.I am a woman who has been with my man for 17 years. We have always enjoyed each other physically and have experienced the many ups and downs that most couples do. Recently, I have found myself paying more attention to keeping him happy and going through a bit of a mid-life phase, wanting to recapture some of the youthfulness of past that I had always taken for granted. Now and then, I began to get the nagging feeling that our sexual repertoire in bed was becoming a bit stale (same 3 positions over and over again) after we had our two children. In doing so, I stumbled upon this handy little deck, bought it, and sat down tonight with my husband to look over the cards without any particular agenda. We noticed that we had already done many of the ones demonstrated. One full hour and 9 new positions later, I emerged from the bedroom feeling as if I had evolved to a higher self. Though we tried various positions and had lots of fun doing it, I never expected my husband to invent a new position from being inspired by the ones we had read!The point to my story is: even if you already think you know a lot of sexual positions (we did), enjoy sex enough (we did, too), and doubt there is much else out there you can do to innovate, this deck will definitely change and rev up the way you make love. Just reading the cards inspires you to want to try different positions (and tonight I had thought I wasn't in the mood!). Recommended position to try: #13 Round The Clock I. Position the man has to be careful in and follow the instructions: #12 The Chain. My personal favorites: #7 and #42.It is an excellent buy for the money. It is a marvelous and cost-effective tool for increasing your enjoyment and mutual fulfillment with your partner, thus improving your marriage or relationship, and having mind-blowing sex that leaves you gasping for air and looking forward to more.
