It changes throughout your cycle

The vagina becomes slightly more firm during your period. Due to cyclic hormonal changes, and a process called keratinization, the tissue is more protected from menstrual fluid which may be irritating.

Bigger than you think

Your clitoris, the primary erogenous mechanism of the woman, is up to 9 centimeters (3 1/2 inches) long!  

Its delicate balance

The vagina is slightly acidic at baseline, with a pH of 3.5-4.5.  This function serves to kill the weakest of the sperm, which are slightly basic and allow only the healthiest sperm into the uterus! Also, when this pH is put off balance, abnormal bacteria can grow which causes vaginitis.

SensitIve and strong 

In addition to THOUSANDS of nerve cells, the clitoris also has muscle. During excitement, this surrounding muscle causes the clitoris to elevate and causes the covering of the clitoris, the hood, to retract. This facilitates the orgasm.

Not all parts are needed

Your cervix has no sexual erogenous nerve endings. Contrary to some beliefs, removal of the cervix has not been proven to decrease sexual pleasure.

The famed G-Spot is real

Your G-spot is closely related to the bladder and contains tissue equivalent to the prostate in males! Pressure on this area during sex can produce a very intensely pleasurable effect.

The earth does shake

The uterus contracts during orgasm. In order to facilitate the uptake of sperm into the uterus where conception will occur in the fallopian tube. Some women experience mild cramping during orgasm, and it is known that orgasm can help to bring on labor in pregnant women.
