of course adultery exist everywhere , but at the west more ....at the west there is no girl stay virgin until 18... and if you gonna married a woman , it rare to got here a virgin .... and most of the times she got the sex before you will at least 10 men .in contrary at muslim nations , most (majority) of the girls and boys stay virgin until the day of mariage .Adultery exist everywhere, but I do not know of any place where it is considered something good. And I was talking about it being caused by pork. That I have seen no proof of.
And as for the example, the women did something wrong but what the man did was far, far worse.
