How do you prevent queefing during sex?

If by queefing you mean fanny farting! I know this can be embarrasing but it is caused by the man pushing too much air into your vagina, when he thrusts into you then it quickly escapes causing the sound. So techincally its not your fault its his so dont be embarrased. But to stop it you could change positions. This can happen often when in a position where your vagina is high in the air. For example if you are in the doggy style position. So try and change positions and hopefully it will eliminate your problem.

My mate and I like the queefing affect, we try to induce maximum amount of air by the piston action of the penis stroke entering the vagina as it seems to also promote a stronger orgasam and to re-energize a softening penis from being inserted for a long period. We turned a negative into a positive. Don't stop it!!! Enjoy it, laugh about it. It could make for better sex.

Face to face spoon position with a complete withdrawl of the penis will produce some large queefs in a relaxed opened waiting vagina. Also inverted missionary position, and doggie positions are maximised for queefing. A relaxed waiting opened and wanting vagina for maximum queefs. The small air pressure difference will not have any ill affects but can feel good.
