Being, uh, mostly straight, I suppose I should start with some straight porn. Not every girl in this genre is a big-haired bleach-blonde with fake tits. Have you heard of Joanna Angel? The 26-year-old Brooklynite started a website called BurningAngel.com, which is a bit like SuicideGirls.com, but dirtier, with better tattoos and fewer piercings. Angel has written, produced, directed, and starred in 20-some "punk" pornos, hardcore flicks featuring twentysomething hipsters, campy plots, and kick-ass music. "Porn 4 YOU, not your Dad" is how Angel signs her photos. She briefly wrote a sex-advice column in Spin magazine, and she contributed a chapter to the book Naked Ambition: Women Who Are Changing Pornography. She's not your typical triple-X idiot. I met her in Vegas at the AVN awards. She's whip smart and a total bitch. She's also hot as hell. The trailer for Joanna Angel's Guide to Humping is posted at www.burningmerch.com. It's the X-rated Breakfast Club John Hughes never made.
