The Aneros Progasm is the newest member of the Aneros family. The Progasm is the largest Aneros to date. It features a newly designed round perineum tab and also boasts a Kundalini K-Tab. The K-Tab adds sensations up and down your back that are complementary to the sensations from the prostate. Mobility is a key to success with our products, and despite its size the Progasm moves inside the man's body to provide a robust prostate massage for incredible pleasure.
