Well I didn't say it came as a surprise. I live in the same world as you do, I see/hear about people having sex at a very young age all around. But just because it's common, doesn't mean I like it. And yes, it's healthy to discuss sex, I agree. Why do you think schools or parents are encouraged to handle that subject with their students or children? No problem with discussing sex.
Unless you're doing that with random strangers, on a forum dedicated to a PS2 game.
I agree with you too, people who knock up their girlfriends at a young age, people who lose respect for themselves after a while, etc etc, are simply stupid. But how do you think people can establish the above? By having sex at a young age. I say wait a while. Enjoy still being a kid while you can, and if you must, start having sex when you're not as influenced by raging hormones anymore, like you are around puberty.
