These are great for strengthening your vaginal muscles as well as providing extra stimulation during intercourse. They may seem intimidating at first; but, once you get the hang of using them, they are sure to become a staple in keeping your sex life healthy and satisfying.

The future isn't as clear as I'd like
These are useless, I highly suggest getting a more expensive, higher quality set of balls. These did not offer any weight or reasons to use my PC muscles to hold them in, since they just stayed up in the back of my body the whole time I used them, even while doing jumping jacks.
