Okay, where do you guys draw the lines?

As a few have guessed, I have an interest in art and art history, but more "from the sidelines" than anything else.

I can/do find the human body to be very artistic (I was a bit surprised to see Star Wars tattoo art show up in the official fan magazine, because I didn't think that would be something they'd cover, but they did).
Anyway I can find human nudes to be specifically artistic and/or stimulating sexually, and I think it depends on pose/subject.
Obviously, someone simply being nude and photographed, drawn etc. (to ME) is one thing, but adding certain poses, certain clothing or lack there of, or certain other objects (you KNOW what I'm talking about here) crosses the line, again, in my mind, from art into erotica, which I would say is art specifically designed to generate a sexual reaction.

And I'll go further to say that I see nothing wrong with this, I think those who do it and those who view it are just normal, sexual human beings.

Any other comments?
