As "body massagers", millions of vibrators have been sold to both men and women. Some people that buy vibrators only use them for pains. However, many people who purchase vibrators marketed as "body massagers" — and, presumably, most people who purchase vibrators marketed as adult toys — use them to get sexual pleasure, most often in masturbation. Vibrators often allow people to achieve orgasm faster and easier and are often said to provide stronger orgasms. They are often recommended by sex therapists for women who have difficulty reaching orgasm by other means. Couples also use them sometimes.
