A yoni egg is an egg-shaped stone that you wear inside your vagina. The crystal acts as a weight resistance, which helps train your pelvic floor muscles - keeping them strong, supple and toned. Wearing a yoni egg for 30 minutes a day can help strengthen your pelvic floor, boost your orgasmic potential, enhance lubrication and improve bladder control. The practice originated in Ancient China 5000 years ago; where the Queen and her concubines wore the Jade Egg to maintain a tight, strong vagina, and give the King epic pleasure in the bed chamber!
