What do you think about TEEN AGE LOVE? Good or No?

What do you think about TEEN AGE LOVE? Good or No?
Many times, 12-year-old girl asked me,
"Hi Seiji. Just I fall in love with a guy."
I answer,
"And...............????"
She said again,
"I wanna love him."
"You mean SEX."
"Yes Seiji."
I was very surprised and said,
"NO. It's the against the law."
Constitution of many countries of this world said,
"To love under 13 or 14 year-old girl is against the law."
We must reconsider WHAT  TEEN AGE LOVE IS.
It's time to do that.
Because their darkness loves are so dangerous not only kids but also Adults.
