The strong metal gives this sounding a tough look, and makes it easy to insert into the urethra. 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 P-spot. Sounding stimulates these nerves directly, offering a great sexual impulse for those who dare. Remember: inspect / wash / sanitize / sterilize. Play safe!
