Editing Labia minora (section)

=== Functioning ===
The inner lips serve to protect from mechanical irritation, dryness and infections of the highly sensitive area of the [[vulval vestibule]] with vaginal and urethral openings in it between them. During vaginal intercourse, they may contribute to stimulation of the whole vestibule area, the clitoris and the vagina of the woman and the penis of her partner. Stimulation of the clitoris may occur through tension of the clitoral hood and its frenulum by the inner labia pulling at them. During sexual arousal, they are lubricated by the mucus secreted in the vagina and around it to make penetration painless and protect them from irritation.

As the [[Urinary meatus|female external urethral opening (meatus)]] is also situated between labia minora, they may play a role in guiding the stream of the urine during [[Urination|female urination]].
