Urethral intercourse

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. 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.[1] By 2014, 26 cases had been documented in the medical literature, many in people with Müllerian dysgenesis who were engaging in urethral intercourse unknowingly.[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 presents a very high risk of bladder infection to the receptive partner.[2][3] It can also lead to permanent dilation of the urethra and incontinence during intercourse. Presenting symptoms of unintentional urethral intercourse include primary infertility, dyspareunia (pain during intercourse), and incontinence.[2] More serious consequences include evisceration via the urethra and bladder rupture.[2]
