What is The Vaginal Opening?

Vaginal Opening vs. Other Nearby Parts

×

It’s important to know the differences between the vaginal opening and other nearby parts of the anatomy, since this area has a few different openings side by side:

• Urethral opening: A very small hole located above the vaginal opening and just below the clitoris. This is where urine (pee) exits the body. The urethral opening is part of the vulva but is not the vagina; it’s the end of the tube from the bladder.
• Vaginal opening: The middle opening in the vulva. This is the entrance to the vagina (the internal canal). It’s larger than the urethral opening. This is where menstrual blood comes out, where objects like tampons or a penis can go in, and where a baby can come out during birth.
• Anus: The opening to the rectum, located below the vaginal opening (closer to the back toward the buttocks). This is where feces (poop) exits the body. The anus is not part of the reproductive system; it’s part of the digestive tract.
• Clitoris vs. openings: The clitoris is not an opening at all – it’s a small sensitive organ at the top of the vulva (where the inner labia meet). It sits above the urethral opening. The clitoris’s only role is sexual pleasure; it doesn’t have a hole and isn’t used for urination or reproduction. Knowing these differences can help avoid confusion. In summary, there are three separate holes in this area (urethra, vagina, and anus), each with a different function.

The Role of the Vaginal Opening

The vaginal opening may appear as just a single part of the body, but it serves multiple important functions as the gateway to the vagina. Here are its main purposes:

• Menstrual flow: The vaginal opening is the exit point for menstrual blood (period blood) to leave the body each month. The blood comes from the uterus (womb), passes through the cervix and vagina, and out of the vaginal opening during menstruation.
• Sexual intercourse and insertion: It’s the opening through which penetration can occur. During vaginal sex, a penis (or fingers or a sex toy) can be inserted through the vaginal opening into the vaginal canal. The vaginal opening also allows for insertion of tampons or menstrual cups during periods, and it’s where a gynecologist might insert an instrument (like a speculum) during an exam.
• Childbirth: The vaginal opening is the last part of the birth canal. During a vaginal childbirth, the baby travels from the uterus, through the cervix and vagina, and out through the vaginal opening into the world. It’s remarkably elastic to accommodate a baby during delivery.
• Sexual pleasure: The opening and the vagina have nerve endings that can contribute to sexual pleasure. For instance, penetration through the vaginal opening can stimulate sensitive areas (though much of the sexual sensation is focused around the clitoris and outer vulva).

All of these functions mean the vaginal opening is a very important part of the female reproductive anatomy. It needs to be flexible (for childbirth and intercourse) and also stay closed/protected at other times to help keep the internal environment healthy.

Normal Variations in Appearance

Just like faces or hands, everyone’s vulva and vaginal opening can look a little different. There is a wide range of normal when it comes to appearance. Here are some common variations:

• Size and shape of labia: The vaginal opening is bordered by the labia (inner and outer lips), and labia come in all sorts of shapes, sizes, and colors. Some people have larger outer labia that cover the opening, while others have larger inner labia that may protrude. Labia may be short or long, somewhat wrinkled or smooth, and often one side is a bit different from the other. These differences are normal and do not affect health or function, though some individuals choose labiaplasty for personal, aesthetic, or comfort reasons.
• Visibility of the opening: In some people, the vaginal opening is more exposed, and you can see a small indentation or hole when the person’s legs are apart. In others, the inner labia might cover the vaginal opening partially or fully when at rest. You might need to gently separate the labia to actually see the opening – this is normal, especially if the inner lips are naturally closer together.
• Coloration: The skin of the vulva, including around the vaginal entrance, can range in color from pink to reddish to brownish or darker, depending on the person’s skin tone. It’s also common for the vulva’s color to change with puberty or age; for example, labia might darken during puberty or after childbirth. These color variations are typically normal.
• Hymen presence: Some vaginas have a more noticeable rim of tissue (the hymen) at the vaginal opening, while others have very little visible hymenal tissue (more on the hymen below). Even the shape of the hymen can vary (it might form a small crescent, ring, or have multiple small openings) – all of which are usually harmless differences.

It’s important to understand that there isn’t one “perfect” look for a vaginal opening or vulva. Vulvas may look different from person to person, but they all have the same basic parts and functions. So, if you or someone else notices that their vaginal opening or labia don’t look exactly like someone else’s, it’s usually nothing to worry about. Normal anatomy can fall within a broad spectrum.

Changes Over Time: Puberty, Childbirth, and Aging

The vaginal opening and surrounding tissues change naturally over the course of a person’s life due to hormones, growth, and events like childbirth:

• During puberty: Before puberty, a girl’s vaginal opening and vagina are small and the tissue is thin. As puberty begins (triggered by hormones like estrogen), the entire genital area matures. The vaginal walls thicken, the area becomes more elastic, and often the hymen (which might have been thick in childhood due to maternal hormones at birth) becomes more stretchy. The vulva, including the labia and vaginal opening, may change in color or size during puberty – for example, the labia might enlarge or darken somewhat. All these changes are part of normal sexual development.
• After sexual activity: If a person becomes sexually active or starts using tampons, the vaginal opening may become a bit more accustomed to stretching. However, the vaginal muscles and opening are quite elastic and usually return to a close-to-normal shape after intercourse or insertion. Regular sexual activity generally does not permanently enlarge the vaginal opening significantly – it’s designed to stretch and then go back to its resting size. That said, someone who is very tense or not aroused might feel the opening is smaller due to muscle tightness, whereas with arousal and relaxation it feels more accommodating.
• Childbirth: This is when the most dramatic changes occur. During a vaginal delivery, the vaginal opening must stretch tremendously (to allow a baby’s head and body to pass). It’s common for the opening and the surrounding skin (perineum) to stretch or sometimes tear during childbirth. After delivery, the vaginal opening may appear wider or more lax than before. In the days right after birth, there can be swelling and the tissue might feel very open, but this swelling subsides within a few days. Over the following weeks, the tissues heal and the vaginal opening will generally become smaller than it was immediately post-birth. However, it might not return exactly to the pre-birth tightness – many people notice a slight, permanent increase in looseness or a change in the shape of the opening after one or more childbirths. This is normal. Doing pelvic floor exercises (Kegel exercises) after recovery can help strengthen the muscles around the vagina and improve tone. If there were stitches or tears, those typically heal in a few weeks. It’s also normal for the color of the vulva to be a bit darker after pregnancy and birth, due to hormonal changes in pregnancy that increase pigmentation.
• Postpartum and breastfeeding: Hormone levels (especially estrogen) drop after giving birth, especially if a person is breastfeeding. This can lead to vaginal dryness until hormone levels stabilize. The dryness can make the vaginal opening and intercourse feel a bit uncomfortable for a while. Using doctor-recommended lubricants can help, and as hormones rebalance (or breastfeeding stops), moisture usually returns to normal.
• Aging and menopause: Later in life, especially after menopause (which typically occurs in midlife), the body produces much less estrogen. Lower estrogen causes the vaginal tissues – including the vaginal opening and canal – to become thinner, drier, and less elastic. This is a natural process called vaginal atrophy. Because of this, an older woman might notice the vaginal opening feels less flexible, and intercourse might become drier or occasionally painful if not addressed. Using vaginal moisturizers or lubricants, and talking to a healthcare provider about estrogen creams or other treatments, can help keep the tissue healthy. On the other hand, in women who have given birth, the pelvic floor muscles might weaken with age, and sometimes the vaginal opening can actually widen or the bladder can droop (prolapse) – if this causes issues like discomfort or incontinence, a doctor can provide treatments or exercises to help. Regular pelvic floor exercises throughout life can maintain muscle tone.
• Other life changes: Significant weight changes, pelvic surgeries, or long-term habits can also subtly affect the vaginal opening’s support structures. For instance, chronic heavy lifting without proper technique might weaken pelvic floor over time. But in general, the most notable changes are tied to hormonal stages (puberty, pregnancy, menopause) and childbirth.

Overall, it’s normal for the vaginal opening to not stay exactly the same from childhood through old age. These changes happen gradually and your body adapts. If changes cause discomfort (like pain with sex after menopause), there are ways to address it by consulting a healthcare professional.

Conclusion

The vaginal opening is a normal part of female anatomy that plays a key role in menstruation, sex, and childbirth. By understanding where it is, how it functions, and how to care for it, you can be more informed about your body. Every person’s anatomy is a little different, and changes occur throughout life – but knowing what’s normal (and what’s not) will help you take care of your health confidently. Always approach this topic with the knowledge that it’s a natural part of the body, and never hesitate to ask a healthcare provider if you have questions or concerns about your vaginal opening or reproductive health. With proper care and awareness, you can ensure that this part of your body stays healthy throughout your life.
