Lyric discussion by -intoit- 

My interpretation is that this song is about a prostitute somewhat tormented about selling herself. It is told partly in the third person with the "she was" and "the girl" referring to herself when she is judging herself. (btw, it is "let the dog IN")

She fights getting attached to her johns, fights wanting them to get attached to her. Fights thinking it is more than purely sex.

But at the end of the day, she knows she is selling sex. That sweet, sweet voice sings to the sailor about the hot cherry pie she has to offer.
