If you're a sounding pro, you'll probably already know what we're about to say, but just in case you aren't, we'll say it again. Sounding (or catheter play, or urethral penetration, if you prefer) can be extremely pleasurable for some penis-owning folks, but it's not something you should try out without lots of time, patience and a great set of high quality tools. We've got the tools, but please, do your research if you're a sounding newcomer!
Okay, that's out of the way so let's talk about the 8mm Steel Urethral Sounding Plug. In solid, subtly weighted stainless steel, the tapered Plug starts off tiny, gradually increasing in width for a very stimulating stretch. A slender neck and beaded tip helps keep everything in place, but still, be sure to keep a close eye on things to avoid discomfort or injury.
Always follow a meticulous cleansing routine before and after using one of these (or any) urethral penetration device. The Plug's nonporous, stainless steel surface is easy to clean - something 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.
*The 8mm Steel Urethral Sounding Plug is approximately 4"/100mm in total length and .3"/8mm at widest.
