IT seems to me that the song is talking about a girl who had been with so many guys, whom she had hurt, this time the guy knows about her and what she does (turn the boys into her bones, (Bones being old dead affairs) he thinks he can take her kiss, her seduction and he does, he gets with her and doesn't fall into the trap of getting hurt, but then afterwards he longs for the kiss and this girl, but knows she is impossible and to him he is just "bones"
