Loose

I like how certain things can change a situation. A pencil and a block of paper can justify people getting naked and posing erotically for you, wearing a lab coat can help you convince people that it is entirely okay to electrocute a puppy and a uniform of authority can make people do silly things

Life drawing is not all it's cracked up to be. The first model I ever had in life drawing class was an old, wrinkly, sagging white guy. He was also the first man I have ever seen naked.

Also, in one of my friend's classes, the model got a boner while doing a longer pose (he was posing on the floor, staring up the skirt of one of the girls in class.) My friend asked the instructor whether to draw the penis flaccid or erect.
