i'd just try different guitars until you find one you are comfortable with.
i know a girl that plays that has a purple ibanez acoustic electric, she's happy with it. chords were real easy on it, but i didn't like it for bends.
mc9 is right about the fingers thing. i had a friend that i played with that had extremely abnormally large hands, but not much flexability or reach. his fingers were about an inch longer, but he couldn't cover as many frets.
practice is best, but it doesn't hurt to try other guitars, and see if you are more comfortable with something else.
