1 Hot: Natalie Portman and Mila Kunis, 'Black Swan' Fox Searchlight Pictures Sure, the ballerinas' tryst might have been a psychologically induced dream, but it still haunts our dreams. In the best way. Read on for more hot (and horrifying) sex scenes in cinema!

2 Hot: Kate Winslet and Patrick Wilson, 'Little Children' New Line Cinema via Everett Collection The sexual tension that builds between Sarah (Winslet, in an Oscar-nominated performance) and Brad (Wilson) for the first half of 'Little Children' is as hot as the summer they met. So when the adulterous pair finally get it on for the first time in Brad's basement laundry room — while their respective kids nap upstairs — the audience felt just as turned on, relieved, and guilt-wracked (well, Brad, anyway) as they did.

3 Hot: Maggie Gyllenhaal and James Spader, 'Secretary' Lionsgate via Everett Collection Please note, 'Fifty Shades of Grey' fans: THIS is how you make BDSM red-hot.

4 Hot: Tom Cruise and Rebecca De Mornay, 'Risky Business' Warner Bros. via Everett Collection Joel's (Cruise) Bob Seger-backed slide might be the film's most famous moment, but re-watch the high school student's first run-in with glamourous Lana (De Mornay), and "Old Time Rock and Roll" instantly becomes as forgettable as disco.

5 Hot: Ryan Gosling and Rachel McAdams, 'The Notebook' New Line via Everett Collection Noah (Gosling) and Allie's (McAdams) sexually charged reunion: Acting as female Viagra since 2004.

7 Hot: Diane Lane and Olivier Martinez, 'Unfaithful' 20th Century Fox Film via Everett Collection The more dangerous Connie (Lane) and Paul's (Martinez) affair gets, the better the sex is. (See: The couple's bathroom tryst.) If only we could bottle all that heat into a snow globe.

8 Hot: Kim Basinger and Mickey Rourke, '9 1/2 Weeks' MGM via Everett Collection Fans might rave about Elizabeth (Basinger) and John's (Rourke) steamy hook-up next to the refrigerator, but the couple's tryst in the rain had more than our taste buds tingling.

9 Hot: Kathleen Turner and William Hurt, 'Body Heat' Warner Bros. via Everett Collection If Ned (Hurt) and Matty's (Turner) witty repartee wasn't enough of a turn on, then their long-awaited roll in the sack — which began when Ned hurled a patio chair through a window to get to Matty — certainly had us warming up.

10 Hot: Angelina Jolie and Antonio Banderas, 'Original Sin' MGM via Everett Collection Because it would be a sin to not include Jolie on this list.

11 Hot and Horrifying: Viggo Mortensen and Maria Bello, 'A History of Violence' New Line via Everett Collection When compared to Tom (Mortensen) and Edie's (Bello) romantic romp at the beginning of the film, the married couple's rough romp — following the revelation that Tom is less a restaurant owner and more a cold-blooded gangster — was indeed horrifying. But when compared to other movie scenes that take place on stairs… yes, it was very hot.

12 Hot and Horrifying: Jason Statham and Amy Smart, 'Crank' Lionsgate To maintain his heart rate — to reverse the lethal effects of the Beijing Cocktail administered to him via a rival — hit man Chev Chelios (Statham) has sex with his girlfriend Eve (Smart) in the middle of a packed Chinatown street. Mortifying… yet the scene has our hearts pumping too.

13 Horrifying: Christian Bale, Cara Seymour, and Krista Sutton, 'American Psycho' Lionsgate via Everett Collection Even more horrifying than serial killer Patrick Bateman's (Bale) violent threesome with two prostitutes? Its Phil Collins score.

14 Horrifying: Graphic Puppet Sex, 'Team America: World Police' Paramount Pictures Yes, the scene — which was so pornographic, it originally earned the film an NC-17 rating — was hysterical, but we'll never look at our children's toys the same way again.

15 Horrifying: Paul Giamatti's Naked Run-In, 'Sideways' Fox Searchlight via Everett Collection An aged Chateau Cheval Blanc might be divine, but walking in on an aged couple having sex — and running out while the naked male other half chases you down — is as horrifying as a Merlot.

17 Horrifying: Madonna, Willem Dafoe, and Wax, 'Body of Evidence' MGM via Everett Collection More proof as to why Cosmo's sex tips should be left ignored.

18 Horrifying: Seth Rogen and Katherine Heigl, 'Knocked Up' Universal via Everett Collection Nothing is quite as harsh a mood killer as your burn-out boyfriend wondering out loud whether he'll harm the baby merely by having sex with you. Well, that and his collection of buds. (Oh, and his stoned friends too.)
