First off, sounding (sometimes known as catheter play, urethral penetration or penis dilation) can be very, very enjoyable. However! It's not something you or anyone should go into without lots of prior research, time, patience and a great set of high quality tools. We've got the tools, but please, please do your research if you're a first timer!
In body safe stainless steel and PVC (ring), the sexily beaded E-Stim Urethral Sounding Kit is pleasantly weighty, extraordinarily sturdy (thanks, steel!) and literally electrifying. When plugged into the included control unit and in position, the Plug delivers slow and quicker jolts of stimulating current. Take your pick from Tap, Vibrating, Massage and Auto modes, while having full control over both speed and intensity. To play with e-stim, you'll need to be wearing the ring in combination with the plug, and both will need to be attached to the power box.
Always follow a meticulous cleansing routine before and after using this (or any) urethral penetration device. The E-Stim Urethral Sounding Kit's stainless steel plug is easy to clean - a feature you definitely want in a urethral device. Always use the highest quality lube with any tool that'll be entering our or your partner's urethra - the best option is a sterile surgical or medical grade water based formula.
Power box requires requires 2 AAA batteries, and the Plug requires 1 AAA battery. All are included. Do NOT use it in or around water.
*The Plug is approximately 5.4"/137.2cm in total, 2.8"/71.1cm insertable and .3"/7.635mm in diameter
