Urethral intercourse or coitus per urethram is sexual penetration of the female urethra by an object such as a penis or a finger. It is not the same thing as urethral sounding, the act of inserting a specialized medical tool into the urethra as a form of sexual or fetishistic activity.

The untrained insertion of foreign bodies into the urethra carries a significant risk that subsequent medical attention may be required.[1] Documented cases of urethral intercourse appear to have occurred between heterosexual couples; a survey of the global medical literature available in 1965 reported accounts of thirteen separate cases.[2] However, the stretching of the urethra required by this form of intercourse has also reportedly resulted in a complete and permanent loss of urethral sphincter control (urinary incontinence); furthermore such intercourse would present a very high risk of bladder infection to the receptive partner.[3] A case of male-on-male urethral intercourse is mentioned in Bonk: The Curious Coupling of Science and Sex by Mary Roach.[4]
