Stop! PinkCherry PSA incoming! Listen up. If you're into 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 4 Ouch! sounds are extra long, ultra lightweight and nice and flexible. All four are identical in shape, but very different in terms of width (ie. stretching/stimulating potential). Take a good look before getting started - and if you're a beginner, definitely go for the thinnest.
Always follow a meticulous cleansing routine before and after using one of these (or any) urethral penetration deice. The Ouch! set's hypoallergenic silicone material can be very thoroughly cleaned - something you definitely want in a urethral device. Boil them or bleach them for reliable sterilization. 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.
