Vagina Myths Debunked: What's Fact and What's Fiction

Most vaginas are roughly as deep as the length of your hand, but they can change shape in certain situations. They cannot be permanently stretched out, but the muscles inside your vagina can weaken.

There are a lot of misconceptions about how the vagina works and how to care for it. Some people think vaginas are a never-ending open space (they're not) or that it only smells when something's wrong (also not true).

Not sure what's fact or fiction? Keep reading for a list of common myths debunked.

1. How long is the vaginal canal?

Not very long. One older study from 2006 found that the average vaginal canal is about 2.5 inches (62.7 mm) long, with a range of 1.5–3.7 inches (40.8–95 mm).

But it can change shape in certain situations, like during sex or childbirth.

2. Does it get longer when you're aroused?

Yes. During sexual arousal, the cervix and uterus lift up and out of the way, allowing the upper two-thirds of the vagina to lengthen for penetration.

If a penis or toy is hitting your cervix, it may mean the body isn't fully aroused yet, or the toy/penis is longer than average (about 5 inches when erect).

3. How does it stretch for childbirth?

The vaginal canal and vaginal opening can stretch significantly to allow a baby to pass. After birth, some people may notice looseness, dryness, soreness, or a wider appearance — all of which are normal.

The vagina usually tightens within a few days and returns close to its pre-birth shape within about six months.

4. Can the vagina get permanently stretched out?

No. Vaginas are naturally elastic and can expand and retract like a rubber band.

Feeling "loose" over time is usually due to weakened elasticity or muscle tone, often related to multiple births or aging.

5. Should I be doing Kegels?

Pelvic floor muscles can weaken from childbirth, surgery, aging, constipation, coughing, or weight gain. Kegel exercises can help strengthen these muscles, which support the bladder, uterus, rectum, and small intestine.

They may also help prevent or control urinary or fecal incontinence.

6. Does the clitoris get bigger, too?

Yes. When you're aroused, the clitoris swells and retracts under its hood. It doesn't grow as dramatically as a penis, but there is a noticeable increase.

7. Do all vulvas look the same?

No. Labia, clitoris size, and skin color vary greatly. Asymmetrical labia, small or large clitorises, and differences in skin tone are all completely normal.

8. Why is the skin darker down there?

It's normal for the genitals to be a different color. Labia may appear brown, pink, red, or purplish, and they may darken temporarily when aroused due to increased blood flow.

If the area stays chronically purple, it could be a yeast infection or chronic irritation such as lichen simplex. A doctor can help confirm.

9. Is pubic hair necessary?

It's a personal choice. Pubic hair isn't required for vaginal health, but removing it can lead to razor burn, cuts, or itching if not done properly.

10. Should I douche to keep things clean?

No. Although douching is still common, doctors recommend against it. The vagina cleans itself naturally.

Douching can disrupt healthy bacteria and pH levels, increasing the risk of infections and STIs.

11. Does it smell different during the month?

Yes — that's normal. Vaginal odor can change with diet, your cycle, or supplements. A slight odor is normal.

But if there's a strong, persistent smell along with thick or greenish discharge, you may have an infection and should see a doctor.

Frequently Asked Questions

How deep is enough during sex?

The vaginal canal is 1.5–3.7 inches long but stretches during sex. Most vaginas can accommodate an average erect penis (about 5 inches).

If penetration feels "too deep," it could be due to insufficient arousal or overly deep thrusting.

Why am I so tight down there?

Most vaginas can stretch as needed. A feeling of tightness may come from:

an overreactive pelvic floor
nervousness or lack of preparation
a thick or inflexible hymen

How small is the vaginal opening?

The opening is typically about 1 inch across, but it stretches easily.

The bottom line

Vaginal depth, scent, color, and shape vary from person to person. If you're concerned about changes like discoloration or odor, talk to a doctor. They can confirm whether everything is normal or provide treatment if needed.

Everyone's vagina is different — and that's completely OK.
