Vibrator use during sexual interactions is common among American adult men and women and is associated with more positive sexual function, according to two studies led by researchers from the Center for Sexual Health Promotion in Indiana University's School of Health, Physical Education and Recreation.

The studies, each of which studied men and women separately, found that approximately 53 percent of women and 45 percent of men aged 18-60 use vibrators. It is the first study of its kind to examine the reasons people use vibrators and the associations with sexual health behaviors and enjoyment.
