The Aneros Progasm is the latest addition to the Aneros family of prostate stimulators. Large and bold, the Progasm provides additional sensations throughout the anal canal while still employing the same famous patented mechanism which causes our products to pivot inside the man's body, rhythmically stroking the prostate for incredible, sublime pleasure. The Progasm has several design features that distinguish it from the other Aneros models. First, the Progasm has a round, ball-shaped perineum tab. This new tab provides a different dispersion of pressure on the perineum. Second, the Progasm has a second tab, which we call the Kundalini Tab, or K-Tab. This tab puts pressure on a known acupressure point located right below the sacrum or tailbone. The pressure from this new tab can provide extra sensations up and down the spine in addition to adding to the whole Aneros experience. Finally, most evident is the size of the Progasm. The Progasm is 25%-30% larger than the Maximus. The thick, contoured head and angled stem provides significant direct contact on the prostate for amazing sensations. Made in USA. Color White.
