"It was so much fun. Everyone was freaked out because I’m nude, but in real life, when I have sex, I’m naked. I don’t have a bra on, and I don’t usually have panties on. So let’s make a real movie! Let’s bring truth to the scene! I didn’t want to be exploited, but this girl—like most girls when they first have sex—doesn’t know what she’s doing. I wanted their first kiss to be sloppy, teenagerish making out. When you’re younger, you think you know what to do, but you really don’t."
