[ouqajfuj] Forbidden knowledge

What are the categories of "forbidden knowledge" that people feel uncomfortable teaching children?
* The feeling of sexual and erotic pleasure
* Techniques of sexual play and erotic entertainment

Hypothesize that the lack of such knowledge gets a lot of people in trouble later in life, causing a lot of harm.  For example, it is that ignorance that allows child molesters to operate.  If the hypothesis is true, it suggests a policy change in education.  However, changing society itself will likely be very difficult because the customs around "forbidden knowledge" exist to define social boundaries, to define society itself.

Create a fictional video of young children speaking casually and comfortably as if well versed in the forbidden knowledge.  It may seem weird, uncomfortable to watch as a viewer, but, as art, it attempts to make the point that that very uncomfortableness is the problem -- you are the problem! -- causing a lot of harm in the real world.
