Strong metal gives this Stainless Steel Ribbed Dilator: Metal 9.5mm sounding a tough look, and makes it easy to insert into the urethrae. Lean and sexy, this ridged urthral sound will make it feel next level for sure. Sounding is exciting, because it's fairly unknown, different, risky and non-traditional. The urethra passes by particularly sensitive areas in the penis head and the g-spot. Sounding stimulates these nerves directly, offering a great sexual impulse for those who dare. Remember: inspect, wash, sanitize, and sterilize. Play safe!
