Accurate to my experiences doing nude figure drawings in art school. It's exciting just for a second then you become super focused on shapes and lines.
I do remember one class where the model was a male. Everyone was focused on their drawing when we all noticed he was 'moving.' The whole class tensed up, and the model was desperately trying to keep their cool. Just as he was about 50% the teacher said "Let's take a break, and if you have anything you need to take care of now is a good time." He leaped from the stand, grabbed his clothes, and ran out of the room. He didn't come back and class ended early. lol.
