it has nothing to do with parenting. Some of the worst offenders are children of highly controlling religious parents.
The problem lies in the culture of the society.
In japan, you ain't fukking period. shyt is so awkward. Kids are kids. Watch some hentai if you need to bust a nut,
In europe, they fukking quick and early but will always use condoms.
In america, there is no culture. So many counter narratives that kids are confused as fukk.
Don't have sex.
Don't use condoms.
Watch millionaires make millions from being sexy.
Glorify said sex symbols.
Give viralness to sex videos.
1 handed claps for being smart.
idolizing stupidity.
This country is so damn mixed in its opinion of how things should be that no form of parenting will help.
In fact, I would go as far as to say parenting is the least effective way to get a child to not be a whore.
The most effective way is to get them into something that makes them feel worthy. If they like it enough, they will focus on it and not have time to whore.
Something like track and field, music, engineering, etc
