Christiane Amanpour has this show on CNN (Sex and Love). She went to Shanghai talking to young people about dating, sex etc.
She interviewed late 20's and early 30's men AND women that had never fukked, been kissed and barely hugged by anyone in their ENTIRE LIVES
.
Some lady ran a school to teach the men and women how to socialize with each other (dancing, hugging etc). She showed a 20+ minute video on "how to have sex" including foreplay.
They got 1.4 billion people but many of the successful young adults that only focused on school and careers have no idea how to even have sex. The average 12 year old breh in America knows that much at least.
