"Porn is something that is a graphic sexual image that conjures up an animalistic reaction in you. You like it or you don't," Violet Blue says.

"Erotica also is graphic sexual imagery, but it has an extra component or several extra components that resonate with the viewer—be it artistic, be it passionate, be it something that emotionally engages you, be it something that parlays into a fantasy that you have about sexuality or the way that you relate to the people on screen."
