The Satisfyer Yoni Power 2 Set consists of three balls in different sizes which you can use to gradually train your pelvic floor. As a beginner, you start with the largest and heaviest, wear while standing, (3 cm diameter, 73 g) and work your way through the medium (2.5 cm diameter, 46 g) to the smallest and lightest (2 cm diameter, 22 g). If you do these pelvic floor exercises regularly, you will quickly notice an effect – as will your lover. Thanks to your strengthened muscles, your partner will enjoy more intense sensations during vaginal intercourse.
