A sound is a sex toy designed to be inserted through the urethra of the penis for sexual pleasure. In some ways the sound is similar to a dildo or digital-anal penetration. Men insert the sounds into their penises for sexual pleasure. The action is mostly a slow and deep penetration unlike a dildo that is inserted and removed repeatedly and often vigorously. These items are common in BDSM and leather fetish community and moreso in the gay subculture therein. Their origins are from a medical instrument of the same name that has become fetishised. However sex toy sounds are not medical ones nor can they be used for any medical procedure.
