A G-spot vibrator is a sex toy with female and male varieties. The female version of the device is built to massage the G-spot, described as a bean-shaped[1] area of the vagina. Some women report that it is an erogenous zone which, when stimulated, can lead to strong sexual arousal, powerful orgasms and female ejaculation.[2] The male version of the G-spot vibrator is used for massaging the prostate for both sexual and health-related reasons.[3]
The female type is of phallus-like shape and especially designed for stimulating the G-spot. It first appeared as a response to complaints that vaginal penetration alone, provided by the penis or otherwise, was generally not enough for women to reach orgasm. Women usually need direct clitoral stimulation to orgasm,[4] [5] and stimulating the G-spot area through sexual penetration, especially in the missionary position, is difficult to achieve because of the special angle at which penetration must occur.[6] The curved structure of the G-spot vibrator attempts to make stimulating the G-spot area possible without awkward body positioning.[7]
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, using the vibrator as a clitoral vibrator in addition to a G-spot vibrator, or, if the vibrator is designed for it, by applying it so that it stimulates the head of the clitoris, rest of the vulva and the vagina simultaneously.[7]
Almost all female G-spot vibrators feature the phallus shape and have a specially curved end for reaching the anterior (front-most) area of the vagina.[7] But there can be also a group of special or exotic G-spot vibrators intended for G-spot stimulation featuring novelty shapes. Generally, G-spot vibrators have a head slightly larger than the glans penis, and are 1–1.5 in (2–3 cm) wide and 5–7 in (12.5–17.5 cm) long.
The prostate massager is a curved device with a round head which is inserted into the anal canal of a male and stimulates the prostate gland, which is also called the male G-spot or P-spot.[8] This can produce a host of different and intense sensations.[8] [3]
G-spot vibrators are usually manufactured from materials that provide a pleasant touch: silicone, jelly, rubber, hard-plastic, or any combination of them.[7]
