Long and thin, gracefully contoured, the Eupho Trident appears like a fine piece of sculpture. The smallest prostate massager in the Aneros product line, it's also the most agile and responsive device they make. The Eupho's gentle curves and Trident refinements will gradually advance experienced users from subtle sensations to orgasms of incomparable power and depth. For sexual intercourse, its smaller frame freely moves through the man's thrusting, for stronger and longer orgasms.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
