>See, that's where you've gone awry. On the assumption that humans did not evolve, but were put on the earth whole made and ripe before the animals came along, then it is 'original' (and even quite 'creative'). And actually, I think it's not sex that is the original sin, but 'lust'.

Ah, but that's just a PC expression for it. If you're not allowed to say "MacBeth", you'll call it "the Scottish play".

So it's somehow OK if two do it without actually wishing to do it? Why would they do it then?
