I need to stop queefing?

So the other night i was "getting intimate" with this guy and i TOTALLY queefed (ie. farted out of my ). Luckily the guy i was with at the time is mostly deaf (he's a war vet)...but i'm kinda promiscuous and i'm worried that the next time i hook up with a guy it'll happen again. It was REALLY embarring...is there something i can do to make sure it doesn't happen again, maybe some sort of exercise or something?
