Vulval lips

The vulval lips, also known as labia, are the folds of skin in front of the vaginal opening and are part of the vulva. A distinction is made between the outer and inner vulval lips. The vulval lips look different in everyone. In some, the inner vaginal lips are longer, in others shorter than the outer lips or have an irregular shape. In some, the outer labia are more heavily padded, in others less so. The vulval lips serve to protect the entrance to the vagina and are sexually sensitive to touch. During sexual arousal, the underlying part of the clitoris (pre-cervix) can swell.
