Sometimes the most intimidating looking sex toys are the most pleasurable! We've crafted our uni-polar Electro Urethral Sounds from 316 stainless steel with a completely smooth finish for enhanced comfort during play. Measuring 5.1 inches in length, it's an ideal beginner's urethral dilator and comes in 5mm, 7mm and 9mm diameters to suit different levels of expertise. Use some lubricant along the length and gently slip the urethral sound into your penis. Once in place you can power up your ElectraStim stimulator to experience intense throbbing and heightended sexual arousal that can be enough to bring you to a powerful orgasm hands free. Use the e-stim sounding probe alongside one of our uni-polar cock rings for intense full-length pleasure. 3 sachets of sterile lubricant and 3 cleaning wipes are also included in each set.
