How common is sex for boys before age 13?

(JAMA Network) Researchers combined data from two US surveys to examine how common it is for boys to have sex before they turn 13. The study included data from nearly 20,000 male high school students and about 7,700 other males between the ages of 15 to 24. Overall, 7.6 percent of the male high school students and 3.6 percent of the other males reported having sexual intercourse before age 13.
