Air that has been pushed into the vagina by the {
penis,
dildo,
fingers...}
during sex often re-emerges with a fart-like sound.
Certain people consider it foul though it is only air.
How you react is very important, because the person who just did it is probably embarrassed and insecure about it.
Here are two helpful ways to
react to a queef:
1) ignore it as if
it is normal or
2)
smile and
chuckle (together) about how interesting our bodies are.
If you do not know the person well it is best to somehow indicate that you are
not offended. Which option is chosen depends on your history with the person and the
general mood of the
lovemaking.
