Queefing

Ever since my 2nd child (born via c section) I queef all the time. Air gets trapped so easily during sex but I don’t even have to be having sex for it to happen which is the annoying part. I can be in a certain position and air will go up and make me have to queef. It’s soooo embarrassing and I just want it to stop 😭 can someone tell me why this might be happening now?
