The perineum is the area between the anus and genitals. This area is located close to several nerves, muscles, and organs, making it sensitive and ultra responsive to stimulation. Perineum massagers use vibrations and/or textured material in order to deliver targeted sensations to your subtle sweet spot, maximizing your orgasmic potential. They are generally used in conjunction with a prostate massager for men, delivering a smorgasbord of erotic pleasure sensations to your lower half.
