Sexuality, Magic, and Perversion by Francis King
One of the first modern-day books to explore orgasm as part of a supernatural rite to achieve Divine Union, Mr. King investigates the use of sexuality by Western and Eastern religious and occult traditions, from fertility cults, tantricism, black masses, Islamic mysticism, templarism, forms to Crowleyan sex magick, and even the work of Wilhelm Reich.
