Little is known about women's use of vibrators within sexual partnerships. Data were collected from a population-based, cross-sectional survey of 2056 women aged 18-60 years in the United States. Partnered vibrator use was common among heterosexual-, lesbian-, and bisexual-identified women. Most vibrator users indicated comfort using them with a partner and vibrator use was related to positive sexual function as measured by the Female Sexual Function Index (FSFI). In addition, partner knowledge and perceived liking of vibrator use was a significant predictor of sexual satisfaction for heterosexual women (p < .01). Clinical and research implications are discussed.
