Moral crusades have zero place in public health and are actively harmful.
Those who marry younger are more likely to divorce. Or lead unhappy lives because they don't divorce to save face, but the marriage is dead.
HPV spreads through oral sex as well by the way.

The biggest barrier to disease transmission reduction, at least here in the US, is uncritical abstinence promoters like yourself. It works, at best, for a small fraction of the population, and leaves the rest woefully unprepared for the biological realities. The best solution to STDs is education. Which, yes, should emphasize that not having sex is an option, but cannot stop there.
Simple data point, though: my wife is from China, grew up in a culture where divorce is basically unheard of. At first she was horrified at what she saw here--but over time she's come to see the marriages of her culture weren't any more successful.

People don't want to hear this obviously. But it is a fact STI transmission has skyrocketed since the so called sexual revolution of the late sixties. Within fifteen years, we has an AIDS epidemic.
