Queefing during sex is completely normal and happens when air gets pushed into the vaginal canal during penetration, then released with an audible sound. You can’t eliminate it entirely, but certain positions, techniques, and long-term habits can reduce how often it happens.
Why It Happens in the First Place
The vaginal canal isn’t a sealed tube. During penetration, the thrusting motion acts like a piston, pushing air inside. When that air has nowhere to go, it gets trapped. Then a shift in angle, depth, or position forces it back out, producing the sound. This is purely mechanical, not digestive. There’s no odor and no gas from your intestines involved.
Several things increase the likelihood. Switching between positions opens the vaginal canal briefly, letting more air in. Positions that tilt the pelvis or elevate the hips create more space for air to enter. Faster or deeper thrusting pushes air in more aggressively. And anything that widens the vaginal opening, like certain angles during oral sex or manual stimulation, changes the pressure inside the canal enough to draw air inward.
Positions That Trap More Air
Any position where your hips are elevated above your torso is the biggest culprit. Doggy style is the most commonly reported one because gravity opens the vaginal canal while penetration pushes air deep inside. Positions where your legs are pulled far back toward your chest have a similar effect.
Positions that keep your torso and pelvis more level tend to trap less air. Missionary with your legs relaxed (not pulled up high), spooning, and being on top all give you more control over the angle and depth of penetration. When you’re on top, you also control the speed, which means less air getting forced in with each thrust.
In-the-Moment Techniques
The most practical thing you can do is reduce the amount of full withdrawal during thrusting. When a penis or toy pulls all the way out and re-enters, it scoops air in with it. Shorter, shallower strokes keep the canal more sealed. If you’re switching positions, try to transition smoothly rather than fully separating and re-entering.
Slowing down during position changes helps too. The rush of pulling apart and reconnecting in a new angle is when most air sneaks in. Taking a beat, keeping bodies close, and re-entering at a gradual pace gives air less opportunity to get trapped.
Some people find that gently bearing down (as if pushing out) before or during re-entry helps expel any trapped air quietly before it builds up enough to make a louder sound. This isn’t guaranteed, but it gives you a small measure of control.
Pelvic Floor Strength and Queefing
Weak pelvic floor muscles are one of the more common contributing factors. These muscles line the base of your pelvis and help maintain tone in the vaginal walls. When they’re weaker, the vaginal canal is slightly more open at rest, making it easier for air to enter during any kind of movement or penetration.
Kegel exercises are the standard recommendation for strengthening these muscles. The technique is simple: squeeze the muscles you’d use to stop urinating midstream, hold for about 10 seconds, then release. Repeating this several times a day over weeks and months gradually improves muscle tone. You won’t see results overnight, but consistent practice can make a noticeable difference over time.
If Kegels on their own aren’t helping, a pelvic floor physical therapist can assess whether your muscles are weak, overly tight, or uncoordinated. Sometimes the issue isn’t weakness at all but tension, and a therapist can tailor a program to your specific situation. It’s worth noting that while pelvic floor rehab is widely recommended by clinicians, the research supporting it specifically for reducing queefing is still limited. That said, stronger pelvic floor muscles benefit bladder control, sexual sensation, and core stability regardless.
After Pregnancy
If you’ve recently had a baby and notice more queefing than before, there’s a clear reason. Pregnancy stretches pelvic floor muscles over months, and vaginal delivery can strain or even tear them further. The hormone relaxin, which loosens joints and tissues during pregnancy, may still be circulating for weeks after birth. Your organs are also physically shifting back into their pre-pregnancy positions, and all of this temporarily changes the tone and shape of the vaginal canal.
For most people, the worst of it improves within two to six weeks postpartum as hormones stabilize and tissues heal. Pelvic floor recovery takes longer. Consistent Kegel exercises can help, but full results often take months. If you’re still experiencing significant issues like air or stool leakage at nine months postpartum, that’s a sign the problem is unlikely to resolve on its own and professional evaluation is a good idea.
When Queefing Signals Something Else
Normal queefing is odorless and only involves air. If the air passing through your vagina has a fecal smell, or if you’re also experiencing urine leaking through the vagina, unusual discharge, frequent urinary tract infections, or pain during sex, these could be signs of a vaginal fistula. A fistula is an abnormal opening between the vagina and another organ like the bladder, colon, or rectum. It allows gas, stool, or urine to pass where it shouldn’t.
Fistulas are uncommon but can develop after childbirth injuries, pelvic surgeries, or radiation treatment. If your queefing is accompanied by any of those additional symptoms, it’s a different situation from normal air trapping and worth getting evaluated.
Keeping Perspective
Queefing is one of the most common and least discussed parts of sex. It happens to virtually everyone with a vagina at some point, and it happens more in certain positions regardless of your anatomy or fitness level. You can minimize it with the techniques above, but completely preventing it isn’t realistic, and chasing that goal can pull you out of the moment more than the sound itself would. Most partners either don’t notice or don’t care. A brief laugh and moving on is often the best response, alongside whichever practical adjustments feel worth trying.
