Does Vagina Size Matter?

Muscle Tone continued...

The vaginal opening likely changes only slightly after birth, Tarnay says. In 1996, doctors began using a measurement called the pelvic organ prolapse quantification system as a way of helping them see how well they were doing repairing that area after childbirth.

This was the first time there was a true before-and-after measurement, Tarnay says. Doctors have used the system to look at populations of women and found that there is a slight increase in the size of the opening after vaginal deliveries. The issue may be more related to muscular weakness or injury in that area, Tarnay says.

“Women who are able to contract the pelvic floor muscles can increase or decrease the size of the hiatus,” he says. “Increasing pelvic floor muscle tone can reduce looseness.”

Kegel exercises can be very effective at strengthening these muscles, Tarnay says, and they may generally improve sex.

A study published in the Australian & New Zealand Journal of Obstetrics and Gynaecology in 2008 found that women who regularly performed Kegel exercises reported greater sexual satisfaction than women who didn’t do Kegels.

The problem with Kegels is that many women don’t know how to do them properly.

“When I ask someone to do a bicep curl, they can do it,” he says. “But a pretty significant subset of the women who say they do Kegels, when I ask them to show me what they are doing, aren’t doing [the exercise] properly or can’t connect between the brain and those muscles.”

To find the muscles you use to do Kegels, either insert a finger into the vagina and squeeze the surrounding muscles or stop the flow when urinating. After you’ve found the muscles, practice contracting them for five to 10 seconds, and then relax. If you can’t hold for that long, work your way up. Repeat the process 10 to 20 times, three times a day. While exercising, be sure to breathe normally and try not to use the muscles in your legs, stomach, or bottom.

Some women sustain nerve injury during birth and can’t feel these muscles. Others just don’t use the proper technique. Tarnay says there are even physical therapists who specialize in helping women perform Kegels properly.

What Really Matters

Worrying about size and whether or not it changes over time is the wrong concern, O’Connor says. Factors like sufficient lubrication and arousal and a good relationship with a partner have a much greater impact on sexual enjoyment for women.

A 2010 study published in the International Urogynecology Journal bears out her opinion. Researchers used medical records, an exam, and questionnaire of 500 gynecological patients aged 40 and older to see if there was a correlation between vaginal length and opening size and sexual satisfaction.

The researchers found that desire, arousal, orgasm, pain, and sexual satisfaction were not linked to vagina size. Instead, the best predictors of sexual inactivity were advanced age, higher BMI, and not being in a committed relationship.

“It is not an exact physical fit you are looking for in terms of sexual function,” O’Connor says. “It is more about the communication between the two partners and making sure both are getting what they need out of the experience and are comfortable.”
