Inner Genital Area

The vagina is the interior portion of the woman's genitals. The vagina is deeply folded and is the area the penis enters during intercourse. The tissue is highly elastic in nature and can accommodate a wide variety of penis sizes. During sexual excitement the vagina narrows at the first third and can expand and lengthen toward the back.

The vagina is typically between 3 to 4 inches deep. If a woman who has a smaller-than-average vagina is matched with a man with a larger-than-average penis (longer than 7 inches), the couple will have to get creative with positions and stimulation techniques to relax the woman, allowing her to open more fully.

Most women and men are not very familiar with the inside of the vagina. It helps to know about these parts — both for sexual enhancement and health reasons. Here are some of the main parts of the vagina.

The inner female genitals, including the hymen and urethra.

The Hymen

The hymen is a flap of tissue that covers the entrance to the vagina, and it is present in most (but not all) virginal women. This thin membrane is broken at the time of first intercourse — or during a strenuous physical activity — and is then dissolved.

Urethra, Urethral Sponge, and G-Spot

The urethra is the canal, or tube, that carries urine from the bladder out of the body. It is short and ends just above the vestibule, or entrance to the vagina, below the clitoris. The urethra runs through the urethral sponge, or G-spot. It is also believed to be the delivery source for female ejaculate.

Many medical professionals still speculate on the existence of the G-spot, or G-area. Most doctors and sex educators now acknowledge that the G-spot exists. It is made up of several glands, including the female prostatic gland, blood vessels, spongy material that holds fluids, and ducts that deliver the fluids out of the body.

This area is located just inside the vaginal opening, on the top part of the vagina, directly beyond the area of rough, bumpy skin that pads the pubic bone. It is behind the pubic bone, tucked against the back side of it.

Cervix and Os

The cervix is the protective tip of the uterus. The os, or entrance to the uterus, is at its center. The cervix can be felt inside the vagina and is sometimes bumped during rough sex, causing pain.

The os typically remains very small, but changes wondrously to stretch and open up to more than 10 centimeters during childbirth. During the conception of a baby, the sperm from the father must travel through the os to get to the uterus and then on to the fallopian tubes. Menstrual blood passes out through the os and then the cervix during a woman's monthly cycle.
