This is pure child abuse, not sex; how could the silly boy said he thought the girl was 15yr. No one "has sex" with girls ages 6-11. That is pure child rape. Any boy aged 15 upward who would even consider molesting the 11-year-old girl, should have his penis amputated right before he's publicly hanged.
The youngest girl ever on record to become pregnant was only 5 years old, for reasons unknown she actually began menstruating at just 18months. This is a medical annomaly and pretty much unheard of.
