We are often asked for even larger Viball models. From Hera's professional experience, we know that 60 mm makes therapeutic sense in many cases, but no more. It is a misconception that a wide vaginal opening is a sign of weak pelvic floor muscles. On the contrary, women with strong sexual activity often have above-average pelvic floor muscles despite a very flexible vaginal entrance. Flexibility and stretchability do not necessarily mean weakness. If you do gymnastics and can do the splits after regular training, this does not mean that your inner adductors in your thighs are weaker. In fact, they are more flexible and therefore more powerful when they are trained at the same time. In a similar way, active sexuality also ensures natural health of the pelvic floor. Regular extreme stretching WITHOUT the opposite pole of strengthening through muscle contraction (e.g. as part of an erotic passion, so-called "stretching addiction") is not harmless, however, because it literally "goes too far". The result can be a prolapse of the bladder or uterus or even a prolapse. Everything has its limits...
That's why we're sticking with a maximum of 60 mm. If you still want more, you can combine sizes.
