When I was growing up, this sort of behavior was “controlled” by the alpha males (jocks, JROTC and FFA) at school. With the clear understanding that such would not be tolerated.

You had nice jocks at your school. At our school they were often the perpetrators.

Well, out here almost all the kids are 4H and they all know which end of the mule eats and which end doesn't by the time they're 8 years old. By the time they're in HS, all the kids are pretty knowledgeable about procreation and respect the results, because they've had hands on experience raising anything from fouls to goats. They also respect it because through the program they're taught the monetary value of their work.
Grab ass in school? sure, it happens but it is always done in fun and jest and if things get a little carried away, the level headed one's set things straight real fast without any of the staff knowing about....at least they believe that line, as we hear about it in a nanosecond
One more thing, the girls are feminine as only a young girl in levis and a pearl buttoned shirt on a fillie can be, but they're tough as iron and the boys treat them with respect. Of course when they start flirting, all bets are off.
