The Aneros Progasm is one of the largest members of the Aneros family to date. It features a specially designed rounded perineum tab and a Kundalini "K-Tab." The "K-Tab" provides additional sensations on the back that complement the feelings from the prostate. It is larger in scale but fully mobile. Mobility is key to the success of Aneros products, and despite its size, the Progasm moves within the man's body to deliver a robust prostate massage for incredible pleasure. The rounded design of the perineum tab ensures comfort. It is large but very maneuverable, making it suitable for advanced and experienced users.
