This is a very fun and lust-filled song about a man admitting that he thinks a particular person is insane, but enjoys the good sex he gets from her.  He mentions about dreaming about doing his desire all night, and how he wants the scratches down his back to go with the rough sex. Yes, he mentions about wanting his sexual conquest to go down on him (with the lyrics "to be a star you have to go down"). This song is meant to be an enjoyable and sexually unhibited type of musical tune. This is a very good rock song that is both wild and catchy.
