The placement of this piercing is very important. It goes through the clitoris either vertically or horizontally. Vertical placement is generally more comfortable for the wearer and a bar or ring can be used. A bar is preferable - the length of the bar will need to allow for swelling and can be up to 16mm length or as short as 8mm depending on the size of the clitoris. Careful measurement is needed and the piercer also needs to be aware that during intercourse the clitoris becomes aroused and swells with blood - this will make a bar that is too short become tight and uncomfortable or even painful.
