I can tell you, from four years of art school, that people tend to make a bigger deal out of nude modeling than it actually is. We had four or five models (men and women) that would rotate between classes, so you'd be drawing/painting/sculpting any model in any given week. The very first class freshman year was a bit awkward for everyone, but after that it just became a part of the routine. By senior year we were on a first-name basis with most of the models. So sometimes, when people found out I was going to art school, I would get a lot of "so you draw naked people all day?" And I would just have to shake my head and laugh, because it became so routine that I didn't think twice about it anymore.
I hope that helps give the artists' side of things
