As a nice girl, I’ve always played by the rules and I’ve never been much for kinky sex. But a little while ago I got curious about what bad girls do between the sheets. I went to the video store and checked out a couple of tapes I’d never even thought about renting before (the kind with the word Cream in the title). Once I got over the shock of the actresses’ oral talents and the scary size of the guys’ equipment, I was amazed to find that I actually liked what I was watching.

I’d always assumed there wouldn’t be a whole lot I could learn about real-world sex from a porno. After all, what girl really wants a leather-clad dominatrix joining in? Much to my surprise, I discovered that porn really does have some insights, and my girlfriends confirm there’s something in it for all of us. The proof’s right here-for further research, consult your local Video Shack.

Porn pointer #1: Go on location.
One of the main reasons blue-movie sex is so titillating is that it almost never takes place in a bedroom. Doctors’ offices, boardrooms, classrooms, and auto-repair shops all make for far more camera-friendly scenery than the duvet-covered bed where most of our real action takes place. And the actors, uh, milk the erotic power of these unconventional sex sites by working local props into the action, finding eye-popping new uses for dentists’ chairs, yardsticks, and duct tape.

Why girls love it: “Getting it on in a setting designed for less-illicit activities makes it seem extra-raunchy,” says Vanessa, 24. “And that eggs on our libidos.”

How to bring it home: Sex in another room won’t flip your gal’s switches unless you really take advantage of the location’s charm. Initiating sex in the kitchen? Open the fridge, take out some gooey chocolate syrup, and lick it off her body 9½ Weeks-style. Going at it in the bathroom? Trickle warm water on her bare skin or grab that bottle of moisturizer and tenderize her ta-tas. “One of the hottest sex sessions I ever had was when my boyfriend and I did it in the living room and we wound up in my rocking chair,” says Erin, 24. “The motion of the chair while we did it-along with the thrill of getting it on in the room where I usually have my friends over-totally rocked my world.”

Porn pointer #2: Shoes stay on.
Girls in pornos always keep at least a little clothing on through even the most complex couplings (and triplings, etc.). Even when they do manage to get all their clothes off, they’re never barefoot. “Fuck me” platform heels always complete the picture.

Why girls love it: When you strip off only the minimum amount of clothing necessary to get the job done, “it makes us feel like you’re indulging in a dirty fantasy of your own-and we’re the star,” explains Jane, 28. “We get off on the knowledge that we’re your dirty little girl.”

How to bring it home: As you well know, girls are obsessed with shoes. Any fantasy specifically involving them is especially likely to float her boat, so wait until she’s totally in the buff, then ask her to put on her sexiest high heels. “When Sean asked me to do him while wearing my four-inch stilettos, it was a huge turn-on,” says Veronica, 28. “I felt so hot wearing them while I was completely naked…and the hotter I feel, the raunchier I get in bed. He even bought me a special pair just for that purpose. Of course, I can’t walk in them, but hey, I don’t have to.”

Porn pointer #3: Assume the position. Er, no…this position.
Porn stars can go through the whole Kama Sutra in a single encounter, but they keep coming back to the position that allows for great extreme closeups: the reverse cowgirl. With the girl on top facing away from her partner, the camera can zoom in and capture an up-close-and-personal view of the graphic action. Which drives the actress wild…

Why girls love it: The reason is twofold, explains Lara, 25. “We know you’re right behind, watching all the action that we’re directing, which makes us feel empowered. Plus, controlling the action means we can shoot for a serious orgasm.”

How to bring it home: Tell your girl how much you love her sexy ass and how much it would turn you on to get to look at it while she rides you. “My boyfriend and I were going at it with me on top when he whispered that I should turn around,” says Erica, 27. “I thought I’d feel like a slut, but I loved it. I could control the rhythm and the depth of penetration, plus touch my own love button for the extra boost I need for a really great orgasm. I’m a total convert now.”

Porn pointer #4: Always keep your closeup in mind.
Guys in pornos give tons of oral sex, a concept dear to our hearts. But it’s how they do it that makes this treat so special. In order to let the camera close to the action, the guy spreads his costar’s legs and holds his head back while using his tongue to lightly tickle her.

Why girls love it: “Sometimes guys make the mistake of burying their face in our crotch the whole time,” says Larissa, 25. “That’s fine at the end, when we’re about to…you know. But while we’re building up, watching you give those light but firm licks to our trigger makes us feel like porn stars.” And that, in turn, makes us perform like porn stars.

How to bring it home: Imagine yourself as a young Ron Jeremy (you wish!), and pretend someone’s filming every move. Keep your head back and don’t go for any deep tongue thrusts. Sound too weird? Use your tongue like a paintbrush to write a message on your girl’s nether regions. “One night my boyfriend popped in a DVD,” says Mandy, 27. “As the guy went down on the girl, my boyfriend mimicked the action. I got to watch him get busy with me and simultaneously watch the action on the TV. It was crazy good.” Keep it light until she’s in the home stretch, then dive in to give her the ultimate send-off.

Porn pointer #5: Get an audience.
NC-17 sex almost always involves more than two people. A happy couple starts making out in the car, and a lucky jogger happens by. They go at it in her office and the Xerox repairman wanders in. The voyeurism adds to the illicit nature of the sex, making it all the hotter.

Why girls love it: Though we girls might not admit it, the idea of a third party stumbling onto our tryst is fascinating. “It makes us feel like high school rebels, making out in the den and praying that Dad doesn’t walk in,” says Jo, 28. “The danger factor is arousing.”

How to bring it home: OK, OK-most girls don’t actually want anyone else to see us doing the wild thing. What heats up sex is the idea we’ll get caught, and you can introduce that without putting your girl in danger of real mortification. Leave the blinds open and do it in the living room (Ding-dong…Jehovah’s Witnesses calling!), or squeeze your hand between her legs while you’re stuck in traffic (cue 18-wheeler air horn). “My boyfriend and I were doing it in the car one night,” says Dawn, 24. “In the middle, he mentioned he hoped a cop wouldn’t wander by. I didn’t really think we’d get caught, but the reminder that we could got me so hot.” Just steer clear of security cameras…or you could wind up starring in a movie of your own.
