The Helix's larger head and angled body produce stronger prostate sensations with special contours and balancing to make it more responsive to your contractions. Its more aggressively shaped profile and Trident Series refinements allow for quicker results with greater ease.The Trident Series introduces Multi-Axial Motion Architecture, or MAMA, our revolutionary feature which allows the Trident to move laterally as well as move up/down and in/out. This extra dimension of movement adds an extra dimension of pleasure, making it easier for a man to reach the Super-O. We think you'll be blown away by it.The Aneros Stimulator allows men to self-administer a prostate massage comfortably and discreetly. Simply through anal kegel exercises, the Aneros's design utilizes a self-pivoting mechanism that stimulates the prostate internally and external via the perineum. This is done completely hands free, allowing a user freedom to explore the sensations in any number of positions.
