1. Boogie Nights Between: Rollergirl (Heather Graham) and Dirk Diggler (Mark Wahlberg)
Dirk, still young and endearingly innocent, arrives at his new boss’s house for a “try-out” and is greeted by the gorgeous Rollergirl. In a flash she is naked and on top of him, Dirk’s new boss watching all the while. As far as teenage fantasies go you don’t get much better, but it’s really the unexpected naivete of the scene that makes it so memorable.
2. The Dreamers Between: Matthew (Michael Pitt), Isabelle (Eva Green) and Theo (Louis Garrel)
There are many memorable scenes, but the one in which the trio lounge in the bath together, titillating each other and the audience, is unforgettably erotic.
3. Secretary Between: E. Edward Grey (James Spader) his secretary Lee Holloway (Maggie Gyllenhaal)
James Spader, n. defn: king of kinky sex. Combine that with Maggie Gyllenhaal in pussy-bow tops and pencil skirts, and sadomasochism has never looked so good. When Attorney E. Edward Grey tells his secretary Lee that there “are seven typing errors on this page”, you know she’s going to be punished for her sloppy work. And even better, you know she wants to be... No wonder spanking went mainstream after this film.
4. Monster’s Ball Between: Hank Grotowski (Billy Bob Thornton) and Leticia Musgrove (Halle Berry)
"Make ... me ... feel ... good" gasps Halle Berry in the build up to the most candid and disturbing of our choices. This is screen sex at its most raw and animalistic. But what really gives the scene power is the context – Berry’s character is having sex with the hard-drinking, racist prison guard that executed her husband. Gives the phrase “screwed up” new meaning.
5. Y Tu Mamá También Between: Zapata (Gael García Bernal), Tenoch Iturbide (Diego Luna) and Luisa Cortes (Maribel Verdú).
Take two gorgeous, sex-obsessed teenage boys, add one luscious 28-year-old Spanish beauty, place on a road trip to one of Mexico’s most beautiful hidden beaches and stir in a good helping of homoeroticism.
6. Mulholland Drive Between: Betty (Naomi Watts) and a mysterious brunette (Laura Harring)
Just how and why the gorgeous Naomi Watts ends up in bed with Laura Harring is never explained, but this is a David Lynch film, it’s not supposed to make sense.
7. American Pie Between: Jim Levenstein (Jason Biggs) and a warm apple pie
Ok, ok, so it’s not a real sex scene, but who can forget Jason Biggs mounting that pie. Or the expression on his Dad’s face?
8. Brokeback Mountain Between: Ennis Del Mar (Heath Ledger) and Jack Twist (Jake Gyllenhaal)
This may be the sex scene where the least amount of skin is shown, but that doesn’t make it any less intense. Who knew two stinky, whiskey drinkin’ cowboys in a tent could be so sexy? Then again it’s got the whole “forbidden love” thing going for it.
9. Basic Instinct Between: Detective Nick Curran (Michael Douglas) and Catherine Tramel (Sharon Stone).
Sure, it’s old. And sure, it’s cheesy. But damn if it isn’t the hottest girl-on-top scene ever filmed for the big screen. Watching Sharon Stone arch her naked body over Michael Douglas is as good today as it was 15 years ago. Pity she has to get out the ice pick and ruin the mood.
10. Unfaithful Between: Connie Sumner (Diane Lane) and Paul Martel (Olivier Martinez)
Intense, obsessive, seductive – Diane Lane shows us how even the happiest married woman can give in to temptation. Blushing and dishevelled on her train journey home, Connie has a flashback of Paul tenderly kissing her stomach, his lips moving down her navel as he carefully removes her panties, sliding them inch by agonising inch down her creamy thighs, while she gasps… " Source: www.24.com/entertainment/movies
