Female masturbation techniques are quite numerous and perhaps more varied than those of males. They are influenced by a number of factors and personal preferences. Techniques include stroking or rubbing of the vulva, especially the clitoris, with the middle, index and/or second fingers. Sometimes one or more fingers may be inserted into the vagina to repeatedly stroke the frontal wall of the vagina where the g-spot is located. (Studies done by Masters & Johnson, however, have shown that only about 10% of women actually have orgasms through vaginal stimulation alone.) [citation needed] Masturbation aids such as a vibrator, dildo or Ben Wa balls can also be used to stimulate the vagina and clitoris. Many women will caress the breasts or stimulate a nipple with the free hand. Anal stimulation is also enjoyed by some because of the thousands of sensitive nerve endings located there.
Lubrication is sometimes used during masturbation, especially when penetration is involved, but this is by no means universal and many women find their natural lubrication sufficient—some even produce more lubricant alone than with a partner, though the reasons for this seem to be primarily psychological.
Women may masturbate in the bathtub, shower and hot tub, sometimes including the use of warm running water to stimulate the clitoris. Common positions include lying on back or face down, sitting, squatting, or even standing. Lying face down, one may straddle a pillow, the corner or edge of the bed, a partner's leg or some scrunched-up clothing and ""hump"" the vulva and clitoris against it. Standing up, the corner of an item of furniture, or even a washing machine, can be used to stimulate the clitoris through the labia and clothing.

Some reach orgasm merely by crossing their legs tightly and clenching the muscles in their legs, which creates pressure on the genitals. This can potentially be done in public without observers noticing. Some prefer to use only pressure, applied to the clitoris without direct contact, for example by pressing the palm or ball of the hand against underwear or other clothing.
A few women can orgasm spontaneously, after experiencing prior sexual arousal, due to intellectual stimulation alone, for instance listening to certain pieces of music. Often, these mental triggers have associations with previous instances of arousal and orgasm. Some women claim to be able to orgasm spontaneously by force of will alone, but that ability, if it exists at all, may not strictly qualify as masturbation as no physical stimulus is involved.
Those who have difficulty reaching orgasm through sexual intercourse may find it easier to achieve an orgasm through masturbation. Sometimes sex therapists will recommend that female patients take time to masturbate to orgasm, especially if they have not masturbated before "
