I won’t lie to you; sounding is not for the faint of heart. When it comes to the long and eclectic list of sexual fetishes, urethral sounding is one of the more risky and dangerous sexual activities out there, but that’s exactly why so many people love it! 

The taboo and thrill of penis sounding is in itself a turn-on for many guys and gals.
This vibrating urethral sound has amazing potential. It is devious enough in its intended purpose, creating some intense urethral sensations. It can also be used as a pinpoint vibrator, with all the fun and exploration that entails. 

Sounding is an form of fetish play that involves inserting a rod or plug up through the penis via the urethral canal.

It can provide a unique and exhilarating sensation and incredible amounts of pleasure. The head of the penis and urethral canal are just packed with ultra sensitive 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, please do your research!
