The Hegar Sound is a urethral dilator with each end a slightly different diameter. The purpose of the sound is to gradually and gently enlarge the urethra using a smooth metal shaft that is inserted into the penis. Urethral play can be an adventurous new facet of your medical fetish or BDSM scene.
Please play safely!
