Is there a way to prevent queefing during sex?

Answer 1

There are things you can try but, be aware, not everyone has success with preventing queefs. Try these:
1. Make sure you are using lots of lubrication.
2. Avoid positions where you must raise your hips and thighs.
3. Practice kegel exercises.
