Okay, before we get into the details of this unique sounding tool from Shot's Ouch! collection, we need to give you a little PinkCherry PSA. If you're already familiar with sounding (or urethral penetration, if you prefer) you'll know that this practice isn't something 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!Sounding is an extreme form of play that involves inserting a rod or plug up through the penis via the urethral canal. For some, it provides a completely unique sensation and lots of pleasure, since the head of the penis and urethral canal is jam-packed with nerve endings. Sounding is also used as a means to direct prostate stimulation, while some penis-owners get off on the extreme nature of sounding. In either case, it's not something to be done on a whim, so if you're interested, again, please do your research!In body safe silicone, the Extra Long Ouch! sound is lightweight, flexible and (optionally) vibrating.
