Urethral Play - pleasuring act of stimulating the urethra, a tube that connects to the bladder and, in men, to the prostate. Depending upon how you play, the stimulation can also increase stimulation in the: bladder, prostate and/or clitoris. They can also be used to prevent ejaculation in men (acting as a 'sperm stopper').
With the help of a Urethral Sound or a Penis Plug, you can excite nerve endings you likely never even considered before. Urethral sounding allows you to take full advantage of every single nerve ending, providing explosive results to give maximum pleasure.
