To those claiming that without this contract....without society's legislating of this union we would decend into an animal like state....all I have to say is that this is simply NOT true.
Again, humans have no maiting season and we have been monogomous since recorded history (wether in the earliest cities, in nomadic tribes...hell even in caves!). Its in our very nature....it happens wether we have these rules or not....neither society, nor even god and religion invented this concept....it predates it all.

Stay safe.

Perfection does not exist. The question therefore, is: what level of imperfection are we willing to settle for?
