The most petite woman I've ever fucked is 4'-4" tall, 71-lbs. I prefer the petite body type. There are also dozens of porn stars in the 4'-5" to 5'-2" range that are considered petite - "spinners."
Most women, independent their height, can accommodate a wide range of girth/length cocks without any trouble. Most of it is a blend of psychological factors, very little with physiology.
