These unique and creative toys are mostly used for female pleasure, though some men also enjoy their use. These vibrators are great for enhancing women sex life. The bullet vibrator is inserted into the vagina where it provides pleasure by stimulating the region surrounding it. The egg vibrator is inserted into the vagina or anus and squeezed with muscular contractions to create a tightening sensation around it, reshaping the vaginal muscles and resulting in stronger orgasms. Kegel balls are also inserted into the vagina to be used as a kegel exerciser (a device to strengthen pelvic floor muscles).
