For women, the most common way to achieve orgasm is by direct sexual stimulation of the clitoris (manual, oral, or other direct friction on the external parts of the clitoris).
Overall statistics indicate that 70–80% of female require direct clitoral stimulation to achieve orgasm. Indirect clitoral stimulation (for example, vaginal penetration) may also be sufficient.
In older research publications, one misconception is that the vagina is completely insensitive. However, areas in the anterior vaginal wall and between the top junction of the labia minora and the urethra are very sensitive.
