With the Aneros Progasm Prostate Massager, men can have their prostate gland massaged, stroked and stimulated. This device is designed to not only insert smoothly into the anus, but is contoured to stimulate the prostate gland with only slight movement. At the same time, the handles on the outside will stroke and massage the perineum, giving the man dual pleasures. A K-tab on the opposite side of the perineum massager offers acupressure point massage. Hands-free usage of the Aneros is possible, since the movement of the device is generated by the contractions of the sphincter muscles. Due to its size, the Progasm is ideal for those more experienced in anal sex. The Progasm measures 4.25″ of insertable length and 1″ in width. It is made of high-grade FDA-approved materials that makes it easy to clean and maintain.
