Urethral sounding is the practice of inserting objects (typically made by metal or silicone) into the urethra for sexual gratification.

If not conducted carefully, sounding carries a risk of irritation, tearing of the urethra, or of urinary tract infection.

[6] Urethral play can involve the introduction of either soft or rigid items into the meatus of the penis (as well as farther in) or vulva.

This action may be directly or indirectly associated with stimulation of the prostate gland and some types of bladder control.

[citation needed] In women urethral sounding can lead to clitoral stimulation.
