I disagree.
First time fell in love with a guy in primary school.
At that age, did you understand that you would never be able to build a family in a monogamous relationship with another boy?
Did you have any sense that everyone else's concepts of romantic love, dating, and marriage are all based on the biological facts of where babies come from?
Chivalry, romance, and monogamy exist because women are smaller and weaker than men, and because women get pregnant.
A father protects his daughter from men who would get her pregnant and then leave her. She needs a man to protect her from other men, because men are generally larger and stronger than her.
Then the father gives that responsibility to her husband on her wedding day, as she publicly announces that she's going to let this one man get her pregnant. And it's specifically announced at the wedding that nobody else is allowed to have sex with the bride and groom, because of where babies come from.
The father has mixed emotions about giving up his duty and trusting his daughter's safety to someone else, but he looks forward to the joy of having grandchildren.
And that is the end goal of romantic love and dating.
A father usually would see no need to give his son's protection to another man, since his son can't get pregnant and should be able to defend himself. Some same-sex couples do imitate this mating ceremony even though they can't actually mate, but it usually involves one person pretending to be the opposite gender so people can more easily pretend that it's similar to a normal wedding.
