Women have three separate openings in the genital and anal area: the urethral opening (where urine comes out), the vaginal opening, and the anus. These three openings are distinct from one another, each with its own function, and they are arranged in a line from front to back.
Where Each Opening Is Located
All three openings sit between the legs, arranged from front to back in this order: the urethral opening is closest to the front of the body, the vaginal opening is in the middle, and the anus is at the back. The urethral opening and vaginal opening are both located within a region called the vulvar vestibule, which is the area between the inner lips (labia minora). The anus is separated from the vaginal opening by a small patch of skin called the perineum.
The term “vulva” refers to the entire external genital area, including the labia, clitoris, urethral opening, and vaginal opening. Many people use the word “vagina” to refer to everything down there, but the vagina is specifically the internal canal. The vulva is the outer anatomy you can see.
The Urethral Opening
The urethral opening is the smallest of the three and the one most people have trouble finding. It sits just above the vaginal opening and below the clitoris. Its only job is to let urine leave the body. A short tube called the urethra connects the bladder to this opening, running about 4 centimeters in length.
One common misconception is that urine exits through the vagina. It does not. The urethra and the vagina are completely separate structures with separate openings. Only urine passes through the urethra.
The Vaginal Opening
The vaginal opening is the middle of the three openings and leads to the vaginal canal, a flexible, muscular tube inside the body. It serves three main functions: menstrual blood exits the body through it, it’s the opening used during penetrative sex, and it’s the passage a baby travels through during vaginal childbirth.
The vaginal opening is partially covered by a thin piece of tissue called the hymen. Hymens vary a lot in shape. The most common types are annular (a ring of tissue surrounding the opening like a donut) and crescentic (a crescent-shaped piece at the bottom of the opening). In rare cases, a hymen can cover the entire vaginal opening, which requires medical attention because it blocks menstrual flow. Some hymens have an extra band of tissue across the middle, giving the appearance of two openings where there is really one.
During arousal, the vaginal walls produce lubrication and the canal expands. These changes are the body’s way of making penetration more comfortable.
The Anus
The anus is the third opening, located at the very back. It is part of the digestive system, not the reproductive or urinary system. The small strip of skin between the vaginal opening and the anus, the perineum, keeps these two openings clearly separated.
Other Tiny Openings You Can’t See
Beyond the three main openings, there are a few microscopic duct openings in the vulvar area that most people will never notice. Two small glands called Skene’s glands sit on either side of the urethral opening. They have tiny openings that release small amounts of fluid, but these are nearly impossible to see with the naked eye. Similarly, Bartholin’s glands near the vaginal opening have small ducts that secrete lubricating fluid. None of these count as separate “holes” in any practical sense, but they do exist as part of normal anatomy.
Why This Can Be Confusing
The urethral opening is small and tucked close to the vaginal opening, which is why many people grow up not realizing there are two separate openings in the vulvar area rather than one. Sex education often glosses over external anatomy, and the widespread habit of calling the entire area “the vagina” makes it harder to understand what’s actually where. A simple hand mirror is enough to identify all three openings on your own body. The urethral opening will appear as a small dot or slit above the larger vaginal opening.
