The vagina remains a mystery to many men and women. In fact, a Cosmopolitan poll found that more than 60 percent of women say they don't know a lot about their vagina, which is unfortunate, because a new study reports that women who feel confident about their vagina have more orgasms.

Most women use the word vagina to refer to her private parts. But technically, the term describes only the narrow canal that runs inside her body from the vulva (the visible area that includes the inner and outer labia, clitoris, and perineum) to the cervix (the lower portion of the uterus).

Stimulation of the Clitoris and G-Spot:
The clitoris is the focus of pleasure sensation for most woman and is usually the place that, when stimulated, will bring her to orgasm.  Stimulation of the G-Spot is necessary as well for some women to achieve an orgasm.  Stimulating both the G-Spot and the clitoris produces the most intense orgasms for all women, and different sex positions allow for different levels of stimulation, or lack of stimulation on either the clitoris or the G-Spot.

Where is the Clitoris and the G-Spot?
The clitoris, or clit, can be quite elusive to men, and even to some women who haven't fully explored their own body. In order to find a woman's clitoris, you'll want to look towards the top of her labia (the outer and inner skin folds of a woman's vulva, or genitals), but stay below the pubic bone. The glans of the clitoris, similar to the head of a man's penis, and even more sensitive, is the nodule you can see when a woman is not aroused and is located between the inner folds of the vulva (labia minora), at the top. The clitoris is just the tip of a branching interior system of erectile tissue that extends towards the vaginal opening. This tissue responds to sexual arousal by filling with blood and becoming harder and erect. As a woman becomes aroused, her clitoris will actually swell and retract underneath the clitoral hood, a flap of skin that is part of her labia minora. The size and shape of the clitoris varies from woman to woman, although its location remains pretty consistent.  The G-spot is an area located on the anterior wall of the vagina. To find yours, place your fingers into your vagina and curl them toward your belly button. Many women report feeling a spongy, thicker area that yields extreme pleasure when stimulated. One sign the G-spot has been found is feeling as though you need to urinate.
