There are three separate openings in the area most people refer to as the “vagina”: the urethral opening, the vaginal opening, and the anus. Each one serves a completely different function, and they are not connected to each other. Many people grow up without learning this basic anatomy clearly, so the question is extremely common.
The Three Main Openings
The external genital area in females is technically called the vulva, not the vagina. The vagina itself is the internal canal. But when most people say “vagina,” they mean the whole area between the legs. That area contains three distinct openings, arranged front to back:
- Urethral opening: This tiny hole sits just below the clitoris. It’s the exit point for urine, connected to the bladder by a short tube called the urethra. It’s small and can be hard to spot.
- Vaginal opening: Located just below the urethral opening, this is the larger opening that leads to the vaginal canal. Menstrual blood exits through it, tampons and other objects are inserted into it, and babies pass through it during birth.
- Anus: The rearmost opening, separated from the vaginal opening by a small patch of skin called the perineum. It is part of the digestive tract, not the reproductive or urinary system.
These three openings belong to three entirely separate body systems. Urine, reproductive functions, and bowel movements each have their own dedicated pathway. Nothing passes between them internally.
Why People Confuse the Openings
The urethral opening and vaginal opening are very close together. In most women, the distance between them is roughly 1 to 1.5 centimeters, which is less than the width of a fingertip. Because the urethral opening is also quite small, many people never realize it’s a separate hole. It’s common to assume urine comes out of the vagina, but it doesn’t.
The outer and inner labia (the folds of skin on either side) partially cover both openings, which makes visual identification even harder. If you’ve never looked closely with a mirror, you may have gone your whole life without seeing the urethral opening at all.
What the Vaginal Opening Looks Like
The vaginal opening varies in appearance from person to person, partly because of the hymen. The hymen is a thin rim of tissue that partially surrounds the vaginal opening. In most people, it naturally has a gap large enough for menstrual flow and tampon use. But there are several variations:
- Septate hymen: A band of tissue runs across the opening, creating what looks like two smaller holes instead of one.
- Microperforate hymen: The tissue covers almost all of the opening, leaving only a very small hole. This can make tampon use difficult.
- Imperforate hymen: The tissue completely covers the opening with no hole at all. This is a medical condition that requires minor treatment because menstrual blood cannot exit the body.
These variations are present from birth and are not caused by sexual activity. A septate hymen can make it look like there are extra holes, but it’s still one vaginal opening partially divided by tissue. If a septate or microperforate hymen causes problems with tampon use or menstruation, a simple procedure can correct it.
Smaller Openings You Can’t See
Beyond the three main openings, there are also tiny gland ducts in the vulvar area that are essentially invisible to the naked eye. Two sets are worth knowing about because they occasionally cause health issues.
Skene’s glands sit on either side of the urethral opening. They produce fluid that lubricates the urethra during urination and may play a role in lubrication during sexual arousal. Some researchers believe these glands are the source of female ejaculation. Their openings are microscopic.
Bartholin’s glands are located on either side of the vaginal opening, closer to the back. They secrete small amounts of fluid that help with vaginal lubrication. You’d never notice them unless one becomes blocked and forms a cyst, which can cause a painful, pea-sized lump near the vaginal opening.
These gland ducts are not “holes” in the way most people mean when asking this question, but they are technically additional openings in the area.
Where the Vaginal Canal Leads
The vaginal opening is the entrance to the vaginal canal, a muscular tube about 3 to 7 inches long. It doesn’t lead to an open space inside the body. The canal ends at the cervix, which is the lower portion of the uterus. The cervix has its own tiny opening that allows menstrual blood out and sperm in, but it’s far too small to fit a finger or a lost tampon through. Objects inserted into the vagina cannot travel past the cervix and get “lost” inside the body.
The vaginal canal is flexible. It stretches significantly during childbirth and contracts enough to hold a tampon in place during everyday use. Its walls normally rest against each other, so it’s not a hollow tube sitting open.
