There are a lot of subjects that [artist id="2389485"]Taylor Swift[/artist] has no problem talking about in interviews, including ex-boyfriends, mean girls and her idea of fairy-tale love. But there's one subject that Swift doesn't think is appropriate.

"It's fine to talk about love publicly, but I think when you talk about virginity and sex publicly, people just automatically picture you naked," she told Allure magazine when asked if she's chosen to remain a virgin. "And as much as I can prevent people picturing me naked, I'm going to."

Choosing not to talk about her sex life is one of the few ways Swift remains private, since she thinks it's important to keep her fans in the know about almost everything. One of the keys to Swift's success is her MySpace blog, on which she's written about everything from her breakup with Joe Jonas to redecorating her bedroom.

"I never would have sold any records if my fans hadn't gone out and bought them. It's so incredible to go out and sign autographs for nine hours straight, for me," she told the magazine. "That's just my favorite thing to do, honestly."

It also helps that Swift is honest about love and broken hearts in her songs. "For some reason, I could never, ever stop writing songs about heartbreak," she said. "Just because as human beings, what we can't have is what we replay in our head over and over again before we go to sleep.

"I have always been fascinated with fairy tales and the idea that Prince Charming is just one castle away," she added about her idea of true love. "And you're gonna run across a field and meet each other in the middle and have an amazing, perfect movie kiss. And it's gonna be happily ever after."

But Swift is also realistic about romance, noting that she's had her heart broken and has turned that pain into musical gold. "I'm the kind of person who needs everything to be justified and needs all of her time to be worth the energy," she said. "So let's say I date a guy who really does nothing but damage me. And you've spent time, you've spent effort, and you've put everything into trying to make that work. And it didn't. So you write a song about it. It was worth everything if you write a song about it."
