There used to be an expression intended to discourage young women from having sex with their boyfriends, suggesting the boyfriend wouldn’t marry them, and it went:
“Why would you buy the cow when you can get the milk for free?”
(I think it’s offensive for parents to call their daughters “cows” like that.)
I am not married, but from what I understand from most people who are, there is no sex whatsoever, or hardly any at all, after marriage. And so I think maybe this expression should be updated to say, this time to young men:
“Why would you buy the cow when you know you won’t get any more milk after you buy it?”
And you could also add:
“And after you buy the cow if you get milk from another cow, you will lose your house, your car, half of your net worth, and you’ll have to pay the first cow a large sum every month for the rest of your life. So why not just get all the milk you can without buying the cow, and then move on to another cow if the current cow insists you buy it?”
