According to the packaging, the Jollie works by stimulating three pressure points. The tip slides under the cervix, creating a "full feeling;" the large bump presses into the G-spot; and the handle wraps around to place pressure on the clitoris (with a ribbed surface for extra stimulation). Let me just tell you: it's all true! It does all that, and it's pretty awesome.By now you're probably thinking, "A large dildo that slides under my cervix and presses on my clit? Sounds great, but how am I supposed to fuck myself with it?" And well you might ask that?because, as it happens, you don't. Rather than doing the old in n' out, the Jollie stays in place, sort of like a vaginal butt plug (for want of a better phrase). For added stimulation, you can press on the base of the toy to create a pulsing sensation, use the handle to gently rock it back and forth, or (my favorite) turn this fabulous dildo into a vibrating all-star by holding your favorite vibe against the base.
