This song makes the most sense when you view the narrator as a gay man leaving a relationship with a man who isn't comfortable with his sexuality. The love interest desires the sex (and lots of it), but always feels bad afterward and blames the narrator. It's a messy situation because the relationship isn't exclusive "your secret life of indiscreet discretions" and "but so does every kiss and tell / who dares to cross your threshold / or happens on your way". The narrator has had enough and just wants out in the most drama-free way possible "I’d turn the screw and leave the screen".
