Kegel exercisers are an awesome way to tighten and strengthen your vaginal muscles. Many exercisers are made of stainless steel, and contain a bulge about midway through the shaft. This is the point where you clench and squeeze your vaginal muscles. Most women find, however, that these exercisers are also awesome sex toys, as the bulge provides tons of exciting stimulation. Whether for tightening and strengthening your vaginal muscles, or having awesome orgasms, these exercisers are a worthwhile investment.
