So what? Besides the obvious fact that for the bulk of human history the marrying age for women was in the mid-teens (a 20 plus year old was considered past her prime) the people who wrote this and consider it scandalous probably think buggering adolescent boys is fine and dandy.

That is a myth, the average for marriage has always been much higher, in 1850 America it was 23 for females, and here is a wiki description of Europe.
""The average age of marriage for most Northwestern Europeans from the late 14th century into the 19th century was around 25 years of age; as the Church dictated that both parties had to be at least 21 years of age to marry without the consent of their parents, the bride and groom were roughly the same age, with most brides in their early twenties and most grooms two or three years older, and a substantial number of women married for the first time in their thirties and forties, particularly in urban areas, with the average age at first marriage rising and falling as circumstances dictated.""
