Sex is more openly spoken about than 40, 50 years ago, and I think probably in comparison to a lot of bands - certainly other contemporary pop girl bands - we're certainly not as suggestive. We talk about sex in the way that we would to our friends. As a girl group, I think it was important not to avoid those sort of things either, because it's about confronting people's idea of what women should be talking about and how they should talk about it. There's no point in shying away from subjects like that, because they exist.
