The piercing is made from just inside the entrance of the urethra through to the top of the vagina.
It's a tricky piercing to perform and its relative rarity can make finding a suitably experienced piercer difficult. Not all women are able to accommodate with this piercing, and it may lead to a small increase in the likelihood of urinary tract infections. However, it often increases female stimulation during sexual intercourse, when motion and pressure on the jewellery cause stimulation in the nerves of the urethra.
