WE often hear a number of myths surrounding the vagina, but many of us never take the time to learn the truth surrounding this very important body part.

Here are some important facts that many persons -- including women themselves -- may not have known.

FACT 1. The vagina cleans itself.

FACT 2. The average depth of a vagina is between three to six inches.

FACT 3. Orgasm relieves menstrual cramps: Having an orgasm relieves menstrual cramps because the vigorous muscle action moves *lo** and other fluids away from congested organs. According to gynaecologist Dr Monique Rainford, "If a woman has an orgasm during her menses, it can relieve cramps and other menstrual pains".

FACT 4. Women are more sexually aroused at menstruation: Dr Errol Daley, gynaecologist at Gynae Associates, said majority of women, although they find it aesthetically displeasing, are more inclined to have sex during their periods, as it is around this time that they are most aroused. "The reason for that may be hormonal or psychological," he said.

FACT 5. Sex won't stretch the vagina: The vagina is incredibly elastic and can fit a supersized penis, yet it always returns to its usual tightness after sex. However, it might be a different story after childbirth, as some women tend to feel looser. Certain exercises, eg, the kegel exercise, can tighten the muscles.

FACT 6. Not having sex won't tighten the vagina: Some persons say the longer you take to have sex, the tighter the vagina will be. This is not true. While the vaginal muscles may be tense at first, penetration gradually loosens it.

FACT 7. The vagina can be exercised: Just as working your biceps firms up your arms, working the main muscle of your pubic region can tone up your vagina. Besides giving you a tighter grip during sex, it also may make it easier to climax. Exercising the muscles means clamping down as if you're stopping your urine flow, hold for 10 seconds, then release. Two sets of 10 to 20 a day will give you noticeable difference in two months.

FACT 8. All vaginas smell: Every vagina has a smell. It tends to be acidic before your period and pungent afterwards. The scent tends to be more noticeable after a workout, because of sweat glands, and during sex, because of the natural lubrication that it produces.

FACT 9. Things can't get lost inside: For persons interested in experimenting with objects and fruits during sex, remember that it's impossible for anything (including tampons) to escape into your uterus since the cervix blocks off access. If it slips out of reach, try fishing it out while squatting and bearing down. However, stay clear of putting food (eg chocolate syrup or whipped cream) up there. The sugar can lead to an infection.
