This is a relatively rare piercing, as placement is difficult and the potential for urinary tract infections may be increased by this piercing. This piercing requires the bearer to have a large enough urethra for it to be viable. This piercing can be extremely sexually stimulating, as its presence stimulates the nerves of the urethra during intercourse or masturbatory activities. It is an advanced piercing and many piercers may not be willing or able to perform it. As noted above, the primary concern with this piercing is that it can lead to an increase in urinary tract infections. While many male genital piercings are transurethral, the longer length of the male urethra reduces the risk of urinary tract infection due to transurethral piercings. In addition, the urethral sounding play often used to enlarge the urethra can be dangerous if done improperly. The presence of this piercing can alter or divert the flow of urine from the body and may require extra attention during and after urination.
