The vaginal opening is a soft, flexible passage located between the urethral opening (where urine exits) above and the anus below. Its size, shape, color, and surrounding tissue vary widely from person to person, and there is no single “normal” look. What you see when you examine yourself depends on your age, hormonal status, whether you’ve given birth, and simply your individual anatomy.
Basic Layout of the Area
The vaginal opening sits in the center of a broader area called the vulva, which includes the inner lips (labia minora), outer lips (labia majora), clitoris, and urethral opening. When you look at yourself with a mirror, the three openings are stacked from front to back: the urethral opening at the top, the vaginal opening in the middle, and the anus at the bottom.
On either side of the vaginal opening, just inside the lower portion of the inner lips, sit the Bartholin’s glands. These are tiny glands that produce small amounts of lubricating fluid. You typically can’t see or feel them at all. If one becomes blocked, it can form a pea-sized or larger lump on one side of the opening, which is a cyst rather than a normal feature.
What the Opening Itself Looks Like
The vaginal opening is partially covered by the hymen, a thin piece of tissue left over from fetal development. The hymen’s size, shape, and thickness are unique to each person and change over time through physical activity, tampon use, hormonal shifts, and sexual activity. In most people, the hymen is a small, flexible ring or crescent of tissue around the edges of the opening, leaving the center open. Some people have very little visible hymen tissue at all, while others have more.
Less commonly, the hymen can take other forms. A microperforate hymen has only a very small opening, while a septate hymen has a band of tissue running across the middle, creating two smaller openings instead of one. An imperforate hymen, which covers the opening completely, is rare and typically discovered during puberty when menstrual blood can’t exit. These variants are structural differences, not something most people would notice by looking casually, but they can affect tampon use or cause symptoms that prompt a medical evaluation.
The tissue around and inside the opening is mucosal, meaning it looks and feels different from the skin on the rest of your body. It’s typically smoother, more moist, and often a deeper pink or reddish tone compared to surrounding skin.
Color, Shape, and Size Variations
Healthy vulvar skin ranges from light pink to deep brown depending on your overall skin tone. It’s completely normal for the inner lips and the tissue around the vaginal opening to be a different shade than the outer lips or the skin on your thighs. This color variation is similar to how the skin on your lips differs from your face.
The labia surrounding the opening come in a huge range of shapes. Some common variations include:
- Asymmetrical inner lips: One side longer or shaped differently than the other.
- Prominent inner lips: The inner lips extend beyond the outer lips, sometimes by an inch or more, with natural folds or extra skin.
- Prominent outer lips: Fuller, rounder outer lips that may completely cover the inner lips, so nothing is visible when the legs are together.
- Curved outer lips: The outer lips curve inward in a horseshoe shape, allowing the inner lips to show slightly at the front.
- Small or open outer lips: The outer lips are set slightly apart, making the inner lips and vaginal opening more visible.
- Small or closed outer lips: Both sets of lips sit closely together, creating a more closed appearance.
None of these shapes is more “correct” than any other. They’re all healthy anatomy.
Normal Discharge at the Opening
You’ll often see some discharge at or near the vaginal opening, and this is a sign the vagina is doing its job of self-cleaning. Healthy discharge is clear, milky white, or off-white. Its texture changes throughout the menstrual cycle, ranging from watery or slippery (especially around ovulation) to thicker and more paste-like at other times. A mild scent is normal, but it shouldn’t be strong or unpleasant.
Discharge that turns yellow-green, gray, or has a cottage cheese-like texture, especially if accompanied by itching, burning, or a strong odor, points to an infection rather than normal function.
How the Area Changes Over a Lifetime
The vaginal opening doesn’t stay the same throughout your life. Hormones are the biggest driver of change.
Before puberty, estrogen levels are low, and the tissue around the opening is thinner and less moist. During the reproductive years, estrogen keeps the vaginal lining thick, elastic, and well-lubricated. The tissue typically looks plump and pink, and the opening is naturally flexible.
After menopause, declining estrogen causes the vaginal lining to become thinner, drier, and less stretchy. The vaginal canal can narrow and shorten, and the tissue may look paler or more fragile. This is sometimes called vaginal atrophy, and it can also cause light spotting, a yellowish discharge, or discomfort during sex. These changes are very common and treatable.
Childbirth can also change the appearance of the opening. The tissue stretches significantly during vaginal delivery, and some people notice the opening looks wider afterward or that small skin tags or scar tissue from tearing or an episiotomy are visible. The labia may also change in size or fullness. All of these are expected post-birth changes.
How to Do a Self-Exam
Getting familiar with your own anatomy makes it much easier to notice if something changes. Find a private, well-lit space, sit or recline comfortably, and hold a small mirror so you can see the vulvar area. Gently separate the outer lips with your other hand.
Work from top to bottom: start with the mons (the soft mound at the front), then look at the clitoris, the inner lips, the outer lips, the vaginal opening, the perineum (the skin between the opening and the anus), and the anus. You can gently touch each area with a fingertip to feel for any lumps or thickening you can’t see. Doing this once a month, or anytime you notice new itching, pain, or a lump, gives you a reliable baseline for what’s typical for your body.
Signs Worth Getting Checked
Most of what you’ll see during a self-exam is normal variation. But certain changes are worth bringing to a healthcare provider:
- New lumps or bumps: A painless or tender lump on one side of the vaginal opening could be a Bartholin’s cyst. Flesh-colored raised spots that look like tiny cauliflower tops may be genital warts. Small fluid-filled blisters can indicate herpes.
- Sores or ulcers: Any open sore on or near the vaginal opening that you can’t explain by an obvious scratch or irritation deserves evaluation, especially if it’s painless (a hallmark of syphilis) or doesn’t heal.
- Skin color changes: White, red, or brown patches on the vulvar skin that itch or don’t go away can sometimes be precancerous changes or a chronic skin condition.
- Persistent irritation: Itching, redness, or soreness that doesn’t resolve within a few days may stem from contact dermatitis (a reaction to soaps, detergents, or fragrances), a yeast infection, or another treatable condition.
Small, painless bumps that have been present for a long time and haven’t changed are often normal oil glands or tiny cysts. But because some sexually transmitted infections also present as painless bumps or sores, anything new is worth a professional look, especially if you’re also experiencing fever, unusual bleeding, or pelvic pain.
