Back in the 18th century men ASKED their wives to go and see a doctor for sexual stimulation...:A brief history of the vibrator: An invention by doctors to relieve them from massaging the female klitoris (a treatment for female hysteria)- which they deemed disguisting, time consuming and only effective in the short run....

"THE VIBRATOR, LADIES AND gentlemen, was introduced as a time-saving piece of medical equipment. Before its invention, hard-working doctors and midwives from antiquity into the last century labored for hours to manually produce the same results a vibrator could elicit in mere minutes. Why were these medical folk rubbing so much clit? To relieve the terrible "hysteria" suffered by one half to two thirds of the female population."
