I think the song is about being in a relationship for a long period of time, and the relationship isn't really bad, but you're just bored with it. The only thing that you still enjoy, and keeps you hanging in(the ropes hang) is the sex. You care about the other person and don't want to hurt their feelings or anything, so you don't break up with them. Hence the lyric "The ropes hang(Sex) to keep us all awake(Keeps the relationship going)"
