If there's one thing everyone in the adult industry wants you to know, it's this: The internet is forever. And whether you only do one scene or 500, people will know. Your family will know. Your church will know. And, even if you're using a pseudonym, it won't be too long before that's figured out too. Should performing sex on film ruin your life? No. Will it? There's a pretty good chance it can.Over the four days I spent at the Adult Entertainment Expo (AEE), I learned a great deal more than I expected about the pornographic film industry. I learned about why some big names got into the business (they love sex, the money's good, etc) and I talked to hopefuls who've done just a few movies and won't ever blow up in the same way a Jessica Drake or a Jenna Jameson has. There's no telling who will be here for the long haul, but every new performer's future will be affected by the adult films they've done and, likely, in a very negative way."People call me and ask me to take things down," Spike Goldberg, the CEO of Homegrown Video (one of the most successful amateur video companies in the business) tells me. "And I say, sure, of course, I'll take it down, but it's on the internet. It won't ever disappear." The silver lining to the internet, Spike says, is that your performances won't quickly be forgotten. But that's cold comfort for the performer who'd like nothing more than to forget.
