The strong metal gives this sounding a tough look, and makes it easy to insert into the urethra. Really feel all the sensations come over you with this thick friend. Sounding is exciting, because itft.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!
