1. Shailene Woodley

"It was both of our first times having an onscreen [sex] scene. It was such a safe, comfortable environment and I am so grateful that it was with Miles, because he was such a gentleman and made me feel very comfortable and nurtured. And I think I made him feel very comfortable and nurtured. It was really sweet. We wanted it to just feel natural." - The Spectacular Now (vanityfair.com)

2. Lena Dunham

"I will be lying there, kind of being slammed by a naked body, thinking, 'I want out of this bed. I want out of this scene. I want out of this life. Who did this to me?' And I realized, I'm my own boss. I've written it. I'm directing it. I'm the person holding myself in sexual slavery." - Girls (popsugar.tv)

3. Jeff Perry

"I get cast gay a fair amount throughout my life. It's not the first time. Matt [Letscher] was kind of like, 'Jeff, um, I'm gonna pretend this is real easy and not a problem, but I've never done this at all.' And so you know, we were awkward for a while. And then he said, 'Let's go for it. Come on. I'm gonna pretend you're my girlfriend, my wife. Here we go.' And we had a lot of fun." - Scandal (accesshollywood.com)

4. Robert Pattinson

"I think the more comfortable you are with each other, the harder it gets to do any kind of really intense relationship scene. You're kind of thinking, 'I don't want to embarrass myself in front of this person.'" - Breaking Dawn (people.com)

5. Mila Kunis

"It's hard to have a sex scene, period. It doesn't matter if it's a friend, a male, a female. You're with 100-something crew members, lighting you, repositioning you, there's no comfort whatsoever." - Black Swan (huffingtonpost.com)

6. Amanda Seyfried

"It was so ... awkward. And you can never destroy that awkwardness; it's always going to be there-even when you're with somebody for the first time in real life. It's just strange." - Chloe (accesshollywood.com)

7. Anne Hathaway

"There is that revoltingly embarrassing moment when you have to take your clothes off in front of strangers. I mean, I don't go to the beach in a bikini for a reason." - Love & Other Drugs (popwatch.ew.com)

8. Leonardo Dicaprio

"When you take on a character like this and you want to accurately reflect the nature of who these people are, you just gotta do it. You can't think about yourself, because it's not me, it's a depiction of somebody else." - Wolf of Wall Street (hollywoodreporter.com)

9. Joseph Gordon-levitt

"It's a pretty technical process. It's built out of lots of little pieces. It's not as if we're over there just making out and someone's shooting." - Don Jon
