The strong metal gives this probe a robust look and makes it easy to insert into the urethra. This probe with three beautiful balls provides extra sensations and will soon become your favourite. Sounding is exciting because it is largely unknown, different, risky and unconventional. The urethra runs along particularly sensitive areas in the head of the penis and G-spot. Sounding stimulates these nerves directly and provides a great sexual stimulus for the braver among us. Please note: inspect, wash, disinfect and sterilise. Play safely.
