The Aneros Progasm is one of the largest members of the Aneros family. It features a specially designed round perineum tab and a Kundalini "K-Tab." The "K-Tab" provides additional sensations on the back that complement the sensations of the prostate. Larger in scale, yet 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 round design of the perineum tab ensures comfort. It is large, yet very maneuverable, making it suitable for advanced and experienced users.
