Cover art for Lowiza lyrics by Lovely Feathers, The

I absolutely adore this song; it could be because I relate to asexuality. Of course, this guy may have only lost interest in being sexual with his wife, but I think if that were the case he'd leave.

As for what it means, I think he thinks he's worthless, because he can no longer please his wife in the bedroom. He may still love his wife, but his children are gone, and he feels no reason to be home if he can't pleasure his wife.
