The Aneros line of male stimulators are the leading and most popular prostate stimulators available. The Aneros Helix has been a customer favorite since its addition to our site. With its unique design and curves, the Aneros Helix not only provides intense anal and prostate pleasure, but relieves congested prostate fluid. Such stimulation has also been found to greatly contribute to increased prostate health. The Helix is largest at the tip (1 1/16" diameter) and 15/16" at the mid-range. Smaller than the Aneros Progasm and the Maximus, the Helix is perfect for those who are starting to explore anal and prostate stimulation. Dimensions: 4" x 1"
