“Women and girls masturbate in an endless list of ways. They may massage their clitoris and vulva with hands and fingers, or rub their vulva up against pillows, bed cloths, stuffed animals, and furniture. Some use water spray, vibrators, and dildos to stimulate their vulva and/or vagina...Some women employ nipple and/or anal stimulation in addition to clitoral and vaginal stimulation. Fantasy often plays a major role in a woman's masturbation activities, as the brain is the largest and most important sexual organ, and as a result physical stimulation alone is frequently not sufficient to produce orgasm.”
