Maybe there's some hidden message, but it seems to me it's just about prostitution and lust. That outside he seems respectable "I'm white (pure) on the outside", but secretly he's obsessed with sex "the truth that lies at home It's on the inside". It also seems like he's actually married but still sleeping around (probably with prostitutes) "What she don't know today, might kill us both tomorrow"- physically but it could also kill their relationship.
