Sexuality, Magic, and Perversion surveys such outre subjects as sex magic, left-hand Tantrism, and the initiates of Aleister Crowley’s Order of Oriental Templars. This fascinating and highly readable book also discusses the role of magical fantasy in contemporary pornography. Appendices cover obscurities such as Ralph Chubb’s homoerotic mysticism and the women bishops of the Mariavite Church in Poland.
Francis X. King was an occult writer and editor who wrote about tarot, divination, witchcraft, magic, sex magic, tantra, and holistic medicine. He was a member of the Society of the Inner Light, an offshoot of the Alpha et Omega, which in turn was an offshoot of the Hermetic Order of the Golden Dawn.
I dont think this book is going to open new doors for anyone anytime soon... if you are already buying books on these subjects this is about as entry level as you can get. Still, even a bad book about sex magic is kinda good... right?
