How would you go about meeting a "normal" girl?
My wife was vanilla, but open minded, when I met her. She's been a "pull-ups by day, diapers by night" girl for about ten years now.
If you are serious check sites like FetLife for meet-ups of your local kink scene. You may not find anyone who is strictly AB/DL, but odds are people there will be more willing to try different things.
