Vaginal flatulence, otherwise known as a queef, sounds similar to passing gas, but comes from your vagina. It can be embarrassing, especially if you’re in the middle of having sex or exercising in public.
“A queef occurs when air is trapped in the vagina and then comes out,” says Sinha. It commonly happens during sex since there are lot of changes happening with vaginal circulation, she adds. There is an increase in blood flow, causing your vagina to expand and then return to its normal size.
Research on vaginal flatulence is sparse, but one study found that vaginal childbirth, low body mass index and young age may increase your risk of vaginal flatulence. Experts say that most queefing studies are based solely on personal reports rather than research.
There isn’t much you can do to prevent queefing. Some experts say Kegel exercises and slower thrusting during sex may help prevent them. You can also avoid sexual positions that require you to be upside down or bent over as these positions can cause air to become trapped. But really, there’s no need to worry about queefing.
