Vibrators have been the friend of the female orgasm for over a century now. Back in the 1800s you could only get access to one via a doctor’s appointment. To cure your irrational woman feelings, hysteria. When they started selling them for home use in the 20th century, companies made up weird, fake uses for them; nail buffing tools,special attachments for vacuum cleaners, etc. One very popular way to market the vibrator was to call it a back massager.
