Satisfyer Yoni Power 1: Pelvic floor training with Ben Wa balls. With Satisfyer Yoni Power 1, you can strengthen your pelvic floor and enjoy even more intense orgasms. Unlike pelvic floor exercises performed with other Ben Wa balls, the Yoni Power 1 focuses not solely on weight, but primarily on size: start with the largest and heaviest ball (3 cm in diameter, 74 g) and progress to the medium (2.5 cm in diameter, 46 g) and finally the smallest and lightest (2 cm in diameter, 22 g). The more often you perform pelvic floor exercises, the stronger your muscles will become, allowing you to hold even the smallest ball. Just 15 minutes a day is enough to achieve an effect that not only you, but also your partner, will notice during intercourse. The ribbed texture of the cylindrical ball also provides stimulation during your workout. More advantages of the Satisfyer Yoni Power 1 Ben Wa Balls: The balls inside the Satisfyer Yoni Power 1 are made of stainless steel and coated with soft, medical-grade silicone, making pelvic floor training especially gentle and hygienic. Thanks to their rounded shape and one-piece construction, the Ben Wa balls are particularly easy to insert and remove using the silicone rings, making the Satisfyer Yoni Power 1 ideal for beginners. Satisfyer Ben Wa balls can also be used for pelvic floor training after childbirth or to help prevent urinary incontinence. Feel free to use the Ben Wa balls in combination with your favorite pressure wave vibrator to further enhance sensations during sensual moments alone. After use, you can clean them with warm water and mild soap and disinfect them with a sexual wellness product cleaner
