The strong metal gives this sounding a tough look and makes it easy to insert into the urethrae. Then let these long silicone sounds from OUCH! slip into your urethra. Sounding is exciting because its 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 to inspect, wash, sanitize, sterilize. Play safe!
