URETHRAL SOUNDING
Involving the insertion of a slender object into the urethra for erotic stimulation, typically by men, often as a form of foreplay or solo play. The act can provide unique sensations and is sometimes associated with BDSM practices due to the potential for temporary discomfort or stretching, which some may find arousing. Urethral sounding can also be a means to explore and stimulate the prostate gland in those who are receptive to it.
