You claim women shouldn't be able to have sex with more men because the husband won't know if the kid is his because our nature grew before contraception.....
Are you aware women have had contraception hundreds of years BEFORE bible times?? They just kept it away from men and told it to their female line. It was pretty effective too. Not 99% like condoms and birth control today, but it was decent and they had things several ways to prevent a baby after sex too. You're a history major so I'm sure you realize that for as long as people have know that sex makes babies, there have been women who have known how to prevent a baby from taking root.
