The external genital organs, collectively known as the vulva, include the labia majora, labia minora, clitoris, and the vestibule of the vagina. The labia majora are the outer folds of skin, while the labia minora are the inner folds. The clitoris is a small, sensitive organ that is crucial for sexual arousal. The vestibule contains the openings to the urethra and the vagina.
