When we orgasm, we flex a muscle called the pelvic floor, a hammock-shaped muscle that hangs between the tailbone and the pubic bone. And just like any muscle, the more we work it, the stronger it gets! Kegels are exercises to strengthen our pelvic floor, leading to stronger orgasms, greater bladder control, and less pain during pregnancy and childbirth. Kegel exercisers are tools designed to be held in the vagina and help tone the pelvic floor. In contrast, dilators are penetrative sexual-health tools that are sold in sets of graduating sizes. Dilators are used to re-train the vagina ad the pelvic floor to accept penetration without pain after surgery, illness, or lifestyle changes.
