Our favorite couple reveals all about getting between the sheets on the big screen -- is this HollywoodLife.com's sexiest gallery ever?

Robert Pattinson and Kristen Stewart are one of the best couples of all time, but their jobs often force them to get intimate with other people! When that happens, there can be some JUICY secrets from behind the scenes! Check out R-Patz and K-Stew's most shocking interviews about sex scenes and tell us, HollywoodLifers -- do YOU think Rob or Kristen has hotter onscreen sex? (Summit Entertainment)

Rob on Cosmopolis sex: "The most difficult [scene] was the one with my bodyguard, played by Patricia McKenzie. At first, we were supposed to see us climax at the beginning of the scene, and then talk after. But [the director] suggested that we talked while we f--ked." (Courtesy Of Entertainment One)

Kristen on stripping down for roles like in The Cake Eaters: ""To watch genuine experience on film is just so much more interesting than seeing [it faked -- like when] you can see the tape holding up the pasties." (Courtesy Of 7-57 Releasing)

K-Stew on acting in racy roles like for Into The Wild: "[The shocking thing is] maybe that it's not, like, shocking." (Courtesy Of Paramount)

K-Stew on Breaking Dawn sex: "It's a funny thing -- as soon as [Bella] becomes a vampire, they kind of ignore their duties instantly. They just want to bone. It's the most ridiculous situation. Really, you just had a child? Really?" (Courtesy Of Summit Entertainment)

Rob's Bel Ami co-star Christina Ricci confessed that he felt self-conscious while shooting: "Rob is just fantastic. All he and I did was make fun of each other the entire time and laugh and make jokes. I'd be like, 'This is so uncomfortable,' and he'd be like, 'I feel awful -- look how ugly I am.' I'd say, 'Yeah -- you're really ugly. I wish I looked like that!'" (Courtesy Of Columbia Pictures)

Rob on Water For Elephants' sex with Reese Witherspoon: "I was actually crying at how sexy Reese was in the scene." (Courtesy Of 20th Century Fox)

Kristen on Breaking Dawn sex: "It is a bit full-on, but it's edited. I see scenes and I think, 'Why is music playing over that?' I was definitely making sounds -- it could be so sexy and it's not. The ratings board breaks it down so technically, and apparently thrusting is a huge problem for the children." (Courtesy Of Summit Entertainment)

R-Patz on Remember Me sex with Emilie de Ravin: "When you end up doing it, you have this little patch on your privates. I didn't really tape it up properly, so I'd spent so long taping it round myself and then literally it falls off within one second and it's taped to the sheet. And you realize the whole crew are looking directly at your butt crack. I can't think of anything exciting for them about this. It gives you a lot of respect for porn stars."
