They are plump enough to act as a cushion during intercourse. They contain sweat- and odour-producing glands, which keep the smooth inner part moistened and give the vulva its highly individual sexual odour.

At the front they join to form the hood of the clitoris and at the back they form the fourchette. They contain sebaceous glands on their outer side and sweat glands on the inner parts, which help with lubrication. During sexual arousal they become engorged with blood (in a similar manner to the penis), which makes them darken in colour and swell to two or three times their normal size. See Fourchette.
