I wear them outside from sex, for training of the perineum. The balls stay in place and do not stand alone. If properly positioned, they do not interfere at all, either by walking or sasseyant. Dailleurs, although we tend to forget them because we do not feel them at all. The vibrations generated by internal beads are imperceptible, even if I miss or I shake my butt. By cons, I can easily see which are effective because their harbor makes me wet. Be careful with vulvar irritation if worn long. Removing them can be a bit painful when you tend to tense up like me, but again, by relaxing, they easily slide to the outside through the cord provided for this purpose.
