Common positions include lying on back or face down, sitting, squatting, or even standing. In a bath or shower a female may direct tap water at the clitoris and vulva. 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.
 

In the 1920s, Havelock Ellis reported that turn-of-the-century seamstresses using treadle-operated sewing machines could achieve orgasm by sitting near the edge of their chairs.

Some can 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.

Do you suffer from Self pleasure guilt? Then read my related article.

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 even 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 self-pleasure as no physical stimulus is involved.

Sex therapists will sometimes recommend that female patients take time to self-pleasure to orgasm, especially if they have not done so before. If you haven't trie d it already girls it is fun and you 'll be suprised how many  young and old  are empowering themselves. Why not stick your toe in the water and give it a go.
