too much air in doggy :,)

Li

So me and my partner both enjoy having sex in a “doggy style” position. I always bend my back, but sometimes I raise up a little and the problem is that sometimes too much air goes in and it starts hurting a lot doing it like this. Is there any way to decrease the air that goes inside? Or how to prevent that? Like maybe he needs to put it in differently or idk. Thanks :)
