I have often wondered if the average person could actually get naked and pose for strangers, to do nude modeling. My guess is, yes, if they felt comfortable and like the artist or photographer wouldn't take advantage of them.
I've done lots of modeling in my life. Much of it nude. Even in front of large groups of art students in big classrooms.
How about you? Could you expose your entire mortal self to strangers for several hours at a time?
