Its as much pragmatic as anything. Girls tend to be lighter and can get out on the floor earlier without sinking. If its a big floor Ill send one of the boys out with them to mitigate their lesser strength and stamina.

Finishing is hard work, especially when its hotter than shit and the cement is flashing. But my girls are total badasses. Tough as nails and dont even blink at the racy male banter (they even join in lol). But they are both beautiful young girls and they are like daughters to me. I wish some of the boys were as tough as they are.
