What do Japanese teenagers talk about?

Question:

Do they talk about sex in middle school in Japan even the females?Kids in every country are alike but I wonder if Japanese kids discuss topics like this.If you are Japanese when you were like 12 did you know about sex and talk about it with friends?

Answer:

I already know sex when I was 10. Me and my friends read this porn manga. lol.. And we used to hide it under some pile of leaves and branches in the trees.
Anyway, yes many teens do talk about sex. It's not new or shocking anymore. Like YOU SAID, kids in every country are alike and they do get curious about it. It's in the development stage of Sigmund Freud. The Genital stage if I'm not wrong.
