Celebrity Quotes on Sex Scenes

After all the anticipation leading up to Kristen Stewart and Robert Pattinson's big Breaking Dawn Part 1 sex scene (which was so hot it had to be taken down a notch for its PG-13 rating), Kristen is jumping headfirst into more steamy roles. In her latest flick, On the Road, which just debuted today at Cannes, she really pushes the sexual boundaries. In the movie, Kristen goes topless, has a threesome, engages in "road head," and manually stimulates her male costars. On the sex scenes, she said, "I love pushing and I love scaring myself. To watch a genuine [sexual] experience on-screen is so much more interesting than when you see the tape holding up the pasties . . . As long as you're being really honest, there's nothing ever to be ashamed of."

Kristen joins the sexy celebs who have been practicing their acting skills between the sheets. And while many actors and actresses — like Lena Dunham — say that onscreen sex isn't quite as enjoyable as the real deal, some stars get really into it. Amanda Seyfried told W magazine she's a big fan of sex scenes. Amanda rolls around in the hay with Justin Timberlake in In Time, but she dishes that her sexiest love-making scene was actually with a lady. She said, "Jennifer's Body is my favorite movie that I've done . . . They had an extreme close-up of [Megan Fox and my] tongues, and I'm telling you, the thing about the scene is that it's actually really sexy. For a young girl to say that about her own sex scene — it must be because it's special. I think Megan and I kissed really well together. We have similar kissing styles and it worked."

From spanking to slobber to ripped pillows, get the first-hand experiences of shooting a sex scene from some of Hollywood's sexiest stars.
