Dear Dr. Andrea,
Last week in your column, Does size matter?, you mentioned the G-Spot. Can you explain what is it and how it works?

Dear Curious,
The G-Spot is an area on the anterior wall of the vagina. If you take the gynecologist's view during an examination, that's the 12 o'clock position. It is located about two inches from the entrance. Unlike the clitoris, it is not a distinct organ.

Rather, the G-Spot is a small area on the vaginal wall that is extremely sensitive to deep pressure. When properly stimulated, it gradually swells to an oval shape about 1 cm. by 2 cm., producing heightened sexual responsivity which may lead to multiple orgasms.

Vaginal orgasms originate from stimulation of the G-Spot and are diffuse with a warm-all-over feeling. Clitoral orgasms originate from stimulation of the clitoris and are more localized to that site. Some women report a blending of the two types of orgasms.

The G-Spot was first noted in the literature by Dr. Grafenberg in 1950. It was rediscovered in 1980 by John Perry, M.Div., Ph.D. and Beverly Whipple, R.N., M.Ed. who named it the Grafenberg Spot. There are still some sex researchers who believe the G-Spot does not exist. However, the women who happily experience these orgasms remain convinced that it does.
