I think the song is a story about a girl who (as the title implies) sells her sex. The line "How's it feel to be so loved, yet so alone?" shows that she's being loved, but no one is there for her when the love is gone. Whereas, the narrator doesn't like this. He's scared to think about where she is, what she's doing. I think this song is about doing anything to feel loved, but you're left feeling more alone than before.
