Satisfyer Yoni Power 1: Pelvic floor training with Ben Wa ballsWith 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 (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.
