If men were marrying to “get sex” then isn’t that the same as the sexual hedonism the article is ostensibly calling out as part of the problem?
No, sex within marriage does not lead to a culture of hedonism. Marriage is part of God’s plan and sex within that context is always virtuous— assuming no-fault divorce is eliminated, which just turns marriage into serial adultery. For men of virtue, the purpose of marriage is much greater than sex, but my comment was intended to mean that even for men of lesser virtue, sex was only culturally acceptable within the bounds of marriage, so they were forced to become virtuous by accepting monogamy.
