Is it normal for females to have a stomach that sticks out?

there's nothing wrong with a little pudge, i find it more attractive and adds character more than if there was just a flat boring nothingness.
but if you don't want it, then it's a combination of not eating any junkfood, and excercise. there's plenty of youtube videos of good ab workouts to follow. and as far as people say doing crunches go, that's good, but it will only flatten out your upper abs, leaving girls with a pooch on the bottom row of abs. to help with that do leg raises/heals to the heavens, and reverse crunches
