Which is why kids grow up with unhealthy attitudes towards sex. 
Exactly. Kids are often taught that sex before marriage is wrong, that it's dirty, and then are somehow supposed to do a 180 after they are married and think that it is good.
Of course, we all heard the numerous lies: If you touch, you will go crazy/blind/grow hair on your palms, become gay, use up all your sperm, etc., and yet, are supposed to then believe these lying adults about other aspects of sex?
American kids deny that their parents have sex, and their parents deny that their kids have any sexual feelings until they are in their late teens, but kids have childish sexual feelings as well. Many kids learn to touch on their own at a early age. (I discovered it by myself around 8, but my friend from Mexico, who was uncircumcised, told me that he first did it around 5).
I remember a friend telling me that she had her first period in 3rd grade. Her mother assuumed that this wouldn't happen until she was in 6th, so she had about 3 before she told her mother, because she thought something was wrong with her. I was freaked out as well the first time I saw something come out from masterbating. My parents, like many, think that it is better to simply not talk about it, and pretend that it doesn't exist, or that it will prevent it from happening, and, in a sense, keep their children from growing up. Unfortunately, their bodies continue to grow up, even if their minds don't mature with it, due to guilt , fear, or ignorance.
A friend from Norway was often asked if she went topless on the beach, or didn't shave her legs. She said yes, to the shock of many prudes. Then she would answer, "You know what I don't understand? You don't go topless to the beach, and think yourself a modest society, but something you have that we don't is inappropriate contentography everywhere. You have it at the supermarket, the gas station, the book store...You have and buy far more inappropriate content, and giggle when I say that we go topless, like you were 5 years old."
That's one of the (many) failures of the abstinence-only movement: it assumes that everyone wants to/will get married. There's a lot of people out there who will never get married. There's a lot of people out there (myself included) who view marriage as an archaic tradition that has little relevance, now that people generally don't enter into marriage for economic reasons.
