Actually qwerty, porn is defined as "creative activity (writing or pictures or films etc.) of no literary or artistic value other than to stimulate sexual desire." I'm not trying to be a smart ass, but I used to argue all the time with my ex-girlfriend over whether or not my tickle videos (featuring fully clothed girls) were porn. Unfortunately for me, she won those fights simply by opening a dictionary. So long story short, porn is ANY material that stimulates you sexually...it has nothing to do with being naked or not. Now I know this could open a whole nother can of worms and raise questions like "Well, what about simple ads featuring a bare foot woman...that turns me on. So is that porn?" And I guess there could be a debate over that. Again, I'm not trying to show you up or anything qwerty, it just seemed like an opportune time to explain it.
