Well thats perfectly confusing. I've always called a butt a fanny.

Gives whole new meaning to a fanny pack......

I notice when I go doggy style it happens more often than any other position. Instead of 'sucking in' whenever he's first entering, push your muscles out like you're trying to push him out of you with just your vaginal muscles. Then when he's inside you, use your muscles to try to keep him inside you so that it stays air tight in there.
