What happens when the contraction ball is put into the body for an hour?

If it is left for too long, it does not have much vaginal contraction, and may also cause imbalance of flora in female vagina, causing bacterial infection, vaginitis and cervicitis. Moreover, the effect of shrinking the ball is not very good, which needs long-term use and has a slow effect.

I use the home Dayue pelvic floor rehabilitation therapeutic instrument, which adopts the principle of neuromuscular electrical stimulation combined with myoelectric biofeedback. It is a professional pelvic floor rehabilitation product approved by the Food and Drug Administration and certified by medical devices. Equipped with abdominal monitoring to help women who can't exert their strength find the right position, which is patented by vaginal tightening. After using it for a while, my husband said that I have become much tighter. Thank you for accepting my answer. If you don't understand, please feel free to ask.
