A further development in the evolution of the male orgasm, the Aneros™ Progasm is an ideal tool for male anal pleasure and incredible prostate massage. Originally created to relieve congested prostate fluid in men, this fantastic piece generates powerful hands-free orgasms with ease and comfort. Medically researched and designed, this amazing piece has been recommended by numerous publications and continues to be lauded the world over for its incredible pleasure possibilities. Ergonomically shaped to comfortably sit in the anus while massaging the prostate and perineum with self-pivoting action, this piece is created from silky smooth FDA approved plastic materials ensuring your safety for healthy play every time. The piece features a larger angled head that tapers gently into a contoured body for precise comfort as you insert and use, ending with a thin neck and two ball-headed abutments on either side. The Progasm works by moving as you flex the internal and external sphincter muscles. As the contractions of these two muscles occur, the piece moves in unison with your body, rubbing and massaging its angled head against the prostate while the front abutment pushes against the perineum for added stimulation. Since this piece is completely automatic, it moves simply by using the pelvic muscles and should not be controlled by applying manual pressure.
