Air in vagina?

So since I've had my baby, I get air in my vagina CONSTANTLY. I only had a small tear that required 2 stitches and it healed completely by my 6 week appointment (5 months pp now). I personally feel tighter than before the baby but every time we have sex it's like deflating a balloon after. And today while squatting down to reach something more came out just randomly. It's more uncomfortable than embarrassing but I'm hoping it'll go away eventually? Anyone else have this issue?
