Feeldoe is the world's first "harnessless" strap-on for women. Try the liberating feeling of not having to adjust the straps. The bulb is inserted into the vagina and the dong extends out at a wonderful natural angle to penetrate a partner. There are ridges at the base of the dong for clitoral stimulation when thrusting. Holding it in gives you stronger orgasms, as the kegel muscle responsible for those gets a good exercise. Because it's silicone, it's flexible, warms to body heat, hypoallergenic and hygienic (boilable and bleachable in a 10% solution). The horse part of the Feeldoe is 7" in length and 1 1/2" in width. The pony part is 3 1/2" long by 1 3/4" in diameter.
