<P> Two primary methods have been used to define and locate the G - spot as a sensitive area in the vagina: self - reported levels of arousal during stimulation, and stimulation of the G - spot leading to female ejaculation . Ultrasound technology has also been used to identify physiological differences between women and changes to the G - spot region during sexual activity . </P> <P> The location of the G - spot is typically reported as being about 50 to 80 mm (2 to 3 in) inside the vagina, on the front wall . For some women, stimulating this area creates a more intense orgasm than clitoral stimulation . The G - spot area has been described as needing direct stimulation, such as two fingers pressed deeply into it . Attempting to stimulate the area through sexual penetration, especially in the missionary position, is difficult because of the particular angle of penetration required . </P> <P> Women usually need direct clitoral stimulation in order to orgasm, and G - spot stimulation may be best achieved by using both manual stimulation and vaginal penetration . Sex toys are available for G - spot stimulation . One common sex toy is the specially - designed G - spot vibrator, which is a phallus - like vibrator that has a curved tip and attempts to make G - spot stimulation easy . G - spot vibrators are made from the same materials as regular vibrators, ranging from hard plastic, rubber, silicone, jelly, or any combination of them . The level of vaginal penetration when using a G - spot vibrator depends on the woman, because women's physiology is not always the same . The effects of G - spot stimulation when using the penis or a G - spot vibrator may be enhanced by additionally stimulating other erogenous zones on a woman's body, such as the clitoris or vulva as a whole . When using a G - spot vibrator, this may be done by manually stimulating the clitoris, including by using the vibrator as a clitoral vibrator, or, if the vibrator is designed for it, by applying it so that it stimulates the head of the clitoris, the rest of the vulva and the vagina simultaneously . </P> <P> A 1981 case study reported that stimulation of the anterior vaginal wall made the area grow by fifty percent and that self - reported levels of arousal / orgasm were "deeper" when the G - spot was stimulated . Another study, in 1983, examined eleven women by palpating the entire vagina in a clockwise fashion, and reported a specific response to stimulation of the anterior vaginal wall in four of the women, concluding that the area is the G - spot . In a 1990 study, an anonymous questionnaire was distributed to 2,350 professional women in the United States and Canada with a subsequent 55% return rate . Of these respondents, 40% reported having a fluid release (ejaculation) at the moment of orgasm, and 82% of the women who reported the sensitive area (Gräfenberg spot) also reported ejaculation with their orgasms . Several variables were associated with this perceived existence of female ejaculation . </P>
