Kegel balls have been used for centuries to strengthen vaginal and pelvic floor muscles. The small, weighted balls come in a variety of different weights and sizes to help you contract and release different muscles with ease. But Kegel balls do more than just whip your pelvic floor into shape. They’re better known for enhancing sexual pleasure — so much so that they’re also called orgasm balls, Venus balls, jiggle balls, geisha balls, love balls, and pleasure balls. Thanks to shout outs on “Broad City” and “50 Shades,” Kegel balls have seen a resurgence in popularity as more people begin to explore their many wonderful — and intimate — uses.
