Did my vagina just fart? What’s going on?

That sound is commonly called a queef, and it is absolutely normal.

Sometimes, while you’re having sex in a certain position, your partner’s penis might push air inside your vagina. 

This accumulated air normally leaves your body without your even noticing it, but on some occasions a certain body position or a deep thrust of the penis forces the air out in a way that produces that sound.

It’s nothing to worry about!
