The face live sex 14 06
This compares to just 4 percent of those who menstruated at 16 or over – considered late for the start of puberty.
Chicago Police announced on Twitter Sunday that they had arrested a 14-year-old boy in connection with the sexual assault of a 15-year-old girl that had been streamed live on Facebook in March.
Another study suggested that for each year menstruation was delayed, the age when a girl got married increased by nine months, according to researchers from Columbia University Mailman School of Public Health in New York.
Menstruating at an earlier age is also linked to having an increased risk of getting sexually transmitted infections (STIs), research suggests.
If the sexual encounter had taken place two months earlier, before the boy's 14th birthday, it would not have been a crime.
We don't know the whole story: it's certainly possible the boy did something worse, something that merits police intervention.
The earlier a girl gets her first period, the younger she will have her first sexual experience, get pregnant and marry.
