Taylor Swift refuses to talk about sex because she thinks people will picture her naked.
The 19-year-old singer - who has previously dated singer Joe Jonas of the Jonas Brothers - has no problem discussing her love life, but draws the line at revealing the intimate details of her relationships.
She said: "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. And as much as I can prevent people picturing me naked, I'm going to."
Taylor admits drawing inspiration from her relationships with men, adding even romances which go wrong are useful.
The 'Love Song' singer said: "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."
The singer admits she loves the idea that everyone has a perfect partner somewhere in the world, but can't shake the idea that emotional turmoil is more exciting than happiness.
She explained to Allure magazine: "I have always been fascinated with fairy tales, and the idea that Prince Charming is just one castle away and it's going to be happily ever after.
"But for some reason, I could never, ever stop writing songs about heartbreak. 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."
