Genital jewellery, also known as sex jewellery and adult jewellery, is jewellery which is designed specifically for wear on or to accentuate the genitals. In a wider sense also nipple rings and some butt-plugs may be called genital jewellery. The practice is not new, however, with genital piercings, designed to stimulate as well as to decorate, being described as early as 300 in The Kama Sutra. Wearing genital jewellery in nudist resorts may sometimes be considered inappropriate because it may be seen as overtly sexual (see Issues in social nudity).
