Dr. Stephen Juan is a scientist, teacher, journalist, and anthropologist. In his new book, The Weirdness of Our Sex, he talks about human sexuality with his usual talent. This time Juan’s special attention was attracted by “oddities”, or rather deviations from the socially accepted rules of sexual behavior. He names and talks in detail about all 113 paraphilias (as these same “extremes” are called according to science) inherent in “homo sapiens.”
