I would recommend photographer Timothy Greenfield-Sanders's book, "30 Porn-Star Portraits" (http://www.amazon.com/XXX-Porn-Star-Portraits-Timothy-Greenf...) to gain a better understanding of how and why people choose to work in the porn industry. In addition to nice photos (of course) it includes essays by porn workers, e.g. Nina Hartley (http://en.wikipedia.org/wiki/Nina_Hartley) and biographical information. This comes in handy next time you encounter someone who claims all porn actresses are drug addicted victims who are either brainless or over-sexed.
