so embarrassing😩

So my boyfriend and I have been exploring with different sex positions. We really like doggy it's great for him but I guess it pushes a lot of air into me and he pulled out and I queefed😫😫. I was soooo embarrassed it didn't phase him he's a sweet guy and we're totally in love and he has the hots for me. But this was so embarrassing for me it didn't happen only once no twice. We finished and I sat up and there goes the air😫. I was mortified both times but he really doesn't care. Any way to prevent this?
