Through the early part of the 20th century, vibrators were used by physicians to stimulate women's genitals, and were also used to stimulate men, either genitally or through rectal attachments. The practice lost favor with physicians, but vibrating devices continued to be sold to the public for their personal use, sexual or otherwise. In her history of vibrators, The Technology of Orgasm: "Hysteria," the Vibrator, and Women's Sexual Satisfaction, Rachel Maines refers to the sexual use of vibrators as being "camouflaged" by their purported health and therapeutic applications. Eventually the camouflage began to wear thin, and for a while vibrators became taboo. In time and with more relaxed attitudes toward sexuality prevailing, vibrators have come into their own as instruments of pure pleasure for both women and men.
