With the Satisfyer Yoni Power 1 you can strengthen your pelvic floor and enjoy even more intense orgasms. In contrast to pelvic floor exercises with other Ben Wa balls, the focus of the Yoni Power 1 is not just on the weight, but above all on the size of the balls: You start with the largest and heaviest ball, wear while standing, (3 cm diameter, 74 g) and work your way through the medium (2.5 cm diameter, 46 g) to the smallest and lightest ball (2 cm diameter, 22 g). The more frequently you do the pelvic floor training, the tighter your muscles become, so you can eventually hold the ball with the smallest circumference. You only have to use the balls for 15 minutes a day to achieve an effect that not only you, but also your sweetheart will notice during vaginal intercourse. The ribbed structure of the round balls also stimulates you during training. The inner balls of the Satisfyer Yoni Power 1 are made of stainless steel and are encased in soft, medical-grade silicone, which makes pelvic floor training particularly gentle and hygienic. Thanks to their rounded shape and seamless processing, the Ben Wa balls are particularly easy to insert and just as easy to remove thanks to the silicone loops - making the Satisfyer Yoni Power 1 ideal for beginners. The Satisfyer Ben Wa balls can also be used for pelvic floor training after giving birth or to prevent bladder weakness.
