An interesting book. Many helpful insights were given on the "how to" of slow sex for staying power and long non-tiring enjoyment. However, a lot of effort would be necessary to come up with even a modicum of results in the practice of energy karezza. Old habits are hard to break--especially in the art of sexual performance. One really needs this book with a willing partner and professional coaching at least in my opinion. But with careful study and consistent effort the art of "Energy Karezza" is attainable. Once attained the benefits are many especially for married partners. Patience would be the key to success here.
