"There's no foreplay in porn. There's no build-up or sexual excitement. You're just sitting around the set, talking with your co-stars about what they had for breakfast that morning or how sad they are because their cat Fluffy got hit by a car. And then the director says, 'Action!' and you have to jump into that state of arousal and have hot sex." Porn star James Deen, who recently teamed up with Lindsay Lohan in The Canyons, on his X-rated sex scenes.
