==Medical Use==
The '''vermilion border''' is the normally sharp demarcation between the lip and the adjacent normal skin. It is the area where the pinkish-red lip tissue meets the facial skin. This border is important in cosmetic and reconstructive surgery, as it defines the shape and contour of the lips.
In a medical context, urethral sounding is used for several purposes. It can be used to increase the size of the urethra, to locate obstructions in the urethra, or to deliver medication directly into the bladder. The procedure is typically performed under local anesthesia.


==Sexual Use==

In the context of sexual play, urethral sounding is often performed as a form of [[BDSM]] play or [[urethral play]]. It can provide unique sensations and can be a source of sexual pleasure for some individuals. However, it is important to note that this practice carries a risk of injury and infection, and should only be performed with sterile equipment and proper knowledge of the procedure.


==Risks and Complications==
== Anatomy ==
The risks associated with urethral sounding include [[urinary tract infections]], [[urethral stricture]], and perforation of the urethra. In severe cases, these complications can lead to long-term damage and may require surgical intervention.


==Prevention of Complications==
The vermilion border is composed of a thin layer of skin that is more translucent than the surrounding facial skin, allowing the red color of the underlying blood vessels to show through. This gives the lips their characteristic color. The border is more pronounced in individuals with lighter skin tones.
To prevent complications, it is important to use sterile equipment and to have a thorough understanding of the anatomy of the urethra. It is also recommended to seek medical advice before attempting this procedure, especially in a non-medical context.
