I live in Britain and this sin is overtaking the culture. Wrong is called right and right is called wrong. Britain is under judgment which is pretty obvious at present. I am not sure if this is a sin between a man and a woman in marriage. We are not forced to have children when we have sex with our wives. The bible says not to defraud each other speaking of not denying the need of sex to the other. So there is more than one reason for it. Russia has done well in this but are not without sin in the way they are murdering women and children in Ukraine. To my mind this is a very reprehensible sin. Those who live by the sword will die by the sword.
