Still it is very wrong. You are still a child being 11, 12, 13, 14 and 15. I even think 16 is waay to young as well. Today's world is meant to destroy and pollute minds with the wrong views on maturity. That girl being 11 years old saying it was great having sex, she will later have a lot of mental issues to be dealing with later. Also taking abortion shows that she isn't even mature having sex, people that have this know that there might happen a pregnancy. Even though she wouldn't have taken abortion, still it doesn't means that she is mature for being a parent.
It is all sick to be seeing young teenagers destroying their lives and opening up for their sexuality even before they are being ready for it. Having sex is meant for enjoyment, yes, but also to make kids. It is inside of marriage too. If you aren't ready to marry, you aren't ready for any sex either. Being a child, is very precious moments also helping you to grow into creativity with your mind, learning to socialize through playing etc... When children feel like they need growing up faster, and become an adult at 11 years old, then something wrong is going on in their minds. There are sure kids that might seem more mature than other kids, but still, they keep on being a kid, and should be treated and seen like a kid.
