The clitoris can be aroused and erect when sexually stimulated. This stimulation of the clitoris can cumulate into an orgasm.

The fleshy padded tissue of the labia majora protect the other external genital organs. They also contain sweat and sebaceous glands, which produce lubricating secretions particularly during sexual intercourse.

During sexual stimulation, the labia minora swell as their blood vessels become engorged with blood. This narrows the vaginal opening and makes them more sensitive to stimulation.
