From NRO:

1 in 4 teenaged girls has a sexually transmitted disease. On the same day that story came out, newspapers reported another study showing that 17 percent of middle-school students had used alcohol within the past year, and 6 percent had been drunk within the past month. A previous study had shown that 47 percent of eighth graders have had alcohol, 20 percent had done so in the last month, and 12 percent had consumed “five or more drinks in a row in the previous 2 weeks.”

The author goes on to point out signs of a recurrence of the tiniest smidge of sexual morality, such as the phrase “walk of shame” to describe the act of going home from an overnight date in clothing that makes the evening’s conclusion obvious.  I don’t know that I agree; the fact that the phrase is so prevalent indicates that this behaviour isn’t unusual.
