Fingering is the use of fingers or hands to sexually stimulate the vulva, vagina or the anus. It may be done for sexual arousal or foreplay, mutual masturbation, or constitute the entire sexual encounter. To "finger oneself" is to masturbate in this manner. It is analogous to a handjob (the manual stimulation of the penis), and may be used as penetrative or non-penetrative sexual activity.
Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina, and may involve one or more fingers.
Massage of the vulva, and in particular the clitoris, is the most common way for a woman to achieve an orgasm. The clitoral glans or shaft may be massaged, usually through the skin of the clitoral hood, using up-and-down, side-to-side, or circular motions. The rest of the genitals are also stimulated by fingering.
Fingering the vagina is often performed in an effort to stimulate the G-spot. The G-spot is reportedly located roughly 5 cm (2.0 in) up on the anterior wall of the vagina, forwards toward the navel. It is described as being recognized by its ridges and slightly rougher texture compared to the more cushion-like vaginal cavity walls around it. Fingering this spot, and in effect possibly stimulating the Skene's gland, is commonly cited as a method that may lead to female ejaculation. Parallels are sometimes drawn with the fingering or other manipulation of the male prostate through the anus.
