Queefing during sex is completely normal. It happens when air gets pushed into the vaginal canal and then released, producing a sound similar to passing gas. It has nothing to do with digestion, carries no odor, and is simply a mechanical side effect of the way bodies move during sex. Nearly everyone with a vagina has experienced it at some point.
Why It Happens During Sex
The vaginal canal is a flexible, closed-ended space. During penetration, whether from a penis, fingers, or a toy, air can get pushed inside with each thrust. Certain positions make this more likely, especially those that angle the pelvis upward or involve deep penetration, like doggy style. When the angle shifts, the muscles relax, or a partner withdraws, that trapped air has nowhere to go but back out. The sound it makes is just air passing through a narrow opening.
It also tends to happen more during position changes. Any time the vaginal canal opens slightly and then closes again, air can slip in. Faster or more vigorous movement increases the likelihood simply because more air is being displaced with each motion. This is pure physics, not a sign that anything is wrong with your body.
The Pelvic Floor’s Role
Your pelvic floor muscles act like a hammock at the base of your pelvis, supporting your bladder, uterus, and rectum. These muscles also help control the opening and closing of the vaginal canal. When they’re strong and toned, they hold the vaginal walls closer together, which makes it harder for air to enter in the first place.
When pelvic floor muscles are weaker, the vaginal canal can open more easily, allowing air to slip in during everyday activities, not just sex. Childbirth is one of the most common reasons pelvic floor tone decreases, since pregnancy stretches and strains those muscles over nine months, and vaginal delivery can stretch them further. Menopause is another factor: lower estrogen levels thin vaginal tissue and reduce muscle tone throughout the pelvic region. Aging in general, chronic heavy lifting, and certain surgeries can also contribute.
If you notice queefing happening more frequently than it used to, weakened pelvic floor muscles are the most likely explanation. Pelvic floor exercises (commonly called Kegels) can help. These involve contracting and releasing the muscles you’d use to stop the flow of urine. Doing them consistently over several weeks can improve muscle tone and reduce how often air gets trapped. A pelvic floor physical therapist can teach you how to do them correctly if you’re unsure whether you’re engaging the right muscles.
After Pregnancy and Childbirth
Many people notice a significant increase in queefing after having a baby, both during sex and during activities like yoga, stretching, or even bending over. This is directly tied to the pelvic floor changes that come with pregnancy and delivery. The muscles and tissues that were stretched during childbirth take time to recover, and for some people, they don’t fully return to their pre-pregnancy state without targeted exercise.
Postpartum pelvic floor rehabilitation can make a real difference. Starting gentle pelvic floor exercises a few weeks after delivery (once cleared by a healthcare provider) helps rebuild strength gradually. Some people see improvement within a few months; others take longer, especially after multiple pregnancies or complicated deliveries.
When Vaginal Gas Could Signal Something Else
In the vast majority of cases, queefing is harmless. But there’s one situation where vaginal gas warrants medical attention: if the air passing from your vagina has a fecal smell, or if you notice stool or unusual discharge coming from the vagina. These are signs of a rectovaginal fistula, which is an abnormal connection between the rectum and the vaginal canal. This opening allows gas and stool from the bowel to pass into the vagina.
Rectovaginal fistulas can develop after childbirth injuries, pelvic surgery, inflammatory bowel disease, or radiation treatment. The symptoms can range from minor (occasional foul-smelling gas from the vagina) to significant (visible stool leakage). This is a treatable condition, but it does require medical evaluation. If your queefing is odorless and only involves air, a fistula is not a concern.
Positions and Practical Tips
Certain adjustments during sex can reduce how much air gets trapped. Positions where the pelvis is tilted downward rather than upward tend to cause less queefing. Missionary and side-lying positions, for example, typically introduce less air than rear-entry positions. Slower, shallower movements also give air less opportunity to enter the canal.
Some people find that keeping penetration consistent, rather than fully withdrawing and re-entering, cuts down on the sound. Using lubrication can also help by creating a tighter seal that makes it harder for air pockets to form. But honestly, the most effective “fix” is simply treating it as what it is: a normal, unremarkable thing that bodies do. It requires no apology and no explanation. If it happens, a brief laugh or just continuing on is all it calls for.
Queefing says nothing about your body’s shape, size, tightness, or health. It happens to people of all ages, body types, and experience levels. The vaginal canal is designed to expand and contract, and any time something enters that space, air can follow.
