I agree with CorrDarklight, I think this has more to do with being taken advantage of. For instance, the line "You'd never die just for me", means you'll fuck whoever will make you die (die is another word for orgasm) even if your already fucking me. "When I'm in you I want to die" kind of means being denied your own pleasure even though the other person gets it. "Use me like I was a whore" is also another clear indicator its someone getting taken advantage of and not just friends with benefits.
