an italian newspaper once circled a new of thirteen years old females who had a real and working circle of micro-prostitutions (showing tits, or genitals, or the like) in exchange for money, brand items, or such.
point is, in the fifties it wasn't like that, in the twenties? in the victorian age?
the word in italian is "pudore", and its the thing lacking. it just seems to be the vogue of the century to go more naked as possible, and more looking as a *pronst* as possible.
problem is that this thing lacks and is seen by other, who are then influenced by that. you read everytime of girls who go anoressic or who follow stupid diets just to look like their stars or such.
if everyone was informed about the risks, instead of having parents (because when you're young, it's the parents duty to inform and educate you in that regard) who go with "flowers and bees" or who simply shrug it off "for when he/she is older" then that's the problem. Because parents can't realize that kids speak in schools. and that schools hold far more than just the same generation of childrens. there are different classes, of different kids, a thirteen years old who see a group of sixteen years old looking at a playboy is interested. Not for the material, but for what the material represents: a way to blend in.
it's the reason some say "not to smoke because it's cool and other do it" and "don't do drugs just to blend in" point is, while mothers and fathers point out immediately to children that "you should not smoke, see that women/man over there? he is going to get lung cancer for that!" (extremism in metaphors, parents are expert in that) or "don't do drugs, you risk overdose and death, or end up a homeless bum on the street, or raped in a disco" , for sex, parents wait. they wait until they think a kid is old enough to understand.
point is, kids can't always go with kids their own age, there will be younger and older ones around.
and each kids wants to do the "grown-up" stuff. to blend in with grown-ups.
information, given fast, quick, and painlessly precise. with all pros and cons and reason, is the best way to avoid problems. an informed person is far less likely to have problems or face consequences than a non informed one.
