IS MY VAGINA A NORMAL SIZE?! Girl Talk with Dr. Rejuvenation

Accommodating and Changeable: The vagina is a very “elastic” organ, says Christine O’Connor, MD, director of adolescent gynecology and well women care at Mercy Medical Center in Baltimore. It is small enough to hold a tampon in place, but can expand enough to pass a child through. This is because the walls of the vagina are similar to those of the stomach, they have rugae, meaning they fold together to collapse when unused, then expand when necessary. “It doesn’t stay one particular size,” O’Connor says. “It changes to accommodate whatever is going on at that time.” The most commonly used measurements regarding the size of vaginas come from Masters and Johnson’s work from the 1960s. They looked at 100 women who had never been pregnant and found that vagina lengths, unstimulated, range from 2.75 inches to about 3¼ inches. When a woman is aroused, it increased to 4.25 inches to 4.75 inches. Regardless of how long the vagina is, the area that is thought to be important for most women’s sexual response is the outer one-third.

Hi, I'm Dr. Aimee Nguyen, also known as Dr. Rejuvenation on social media. Today we're going to answer some commonly asked questions, one of which is, is the size of my vagina normal? Totally is. So as we age, you can find that the vaginal canal can actually stretch out and dilate, but it also can contract. So the vagina's made out of very elastic tissue, which can stretch, but then the pelvic floor muscles, which are underneath that will contract and bring it back to its normal size. But with childbirth, for example, the vagina definitely can stretch out and dilate and it may not feel as tight as it used to before you had kids. Other things that can change the size of the vagina, for example, is just with intercourse. With sexual arousal, the vaginal glands produce hormones that actually help relax the vagina. So initially with penetration, you may feel like it's nice and tight, but the more aroused that you get, the more those pelvic floor muscles may relax and the vaginal canal can actually dilate. So you may feel like things are a little bit more stretched out, but then, believe it or not, it goes right back to where it used to be.

The average length of the vagina varies anywhere from three to seven inches. So three inches is about the size of a MAC lipstick, which isn't very big if you think about it, but the vagina can actually accommodate a menstrual cup, but it also can actually dilate to accommodate a baby's head through that vaginal birth canal. The first two to three inches of the vagina is the part that actually has sensation, but the distal part of the canal doesn't, so that's why you can actually insert a tampon, for example, and totally forget about it.

So basically, the size of the vagina can vary as we age, but all of which is completely normal.
