Ben Wa balls are small round balls that are used for strengthening the vaginal wall or for sexual stimulation in women. These balls are generally hollow and contain a small weight inside. Using lubrication, the Ben Wa balls are inserted into a woman's vagina and held there from anywhere from one minute up to an entire day.
Ben Wa balls are also known as Geisha balls, Burmese bells, Benoit balls, orgasm balls, Venus balls, love balls, Kegel balls, pleasure balls, Kegel spheres, or rin no tama.
