I think you should stop extrapolating your personal preferences to half of the world's population, too. Something as varying as sexual attraction can't be reduced to a fixed trait that "nature" has figured out. Indeed we don't choose what we like, and that is fine. You don't have to rationalize your preferences to anyone.
Sadly he is right. Men choose younger as a sign of being able to reproduce. Women, older with high status, because they can reproduce until very late.
Women can't. Over the age of 30 there's severe risk.
