Male and Female's different responses to Intimidation

Well, another questions about 'Human' is keeping me up all night. Might as well write it down and maybe collect some opinions.


Question : Male and Female's different perception / responses to intimidations.

Scenarios based on my experiences :

- A male teacher intent to intimidate the class for the whole semester. All boys goes quiet, some girls giggles.
Boys response : Holy shit. He meant to ruin our lives, and he can. We gotta watch out.
Girls response : Hahaha, I know! He's hilarious!

- When topic about 'Death' occurred occationally,
Some women showed highly negative responses. A few even moved the table when they heard the word.
Some male also showed negativity. But rather more ethusiastic about expressing their own histories or expectations, if not joking about it.

- When dancing in crowd, or play physically upclose.
Occasionally girls jiggle rubs their butts on each other without much difficulty. Then some does it to men then realize how awkward it was afteward, unless the men was highly trained for it already.
Men rubbing their butts on each other? Never seen one. Probably does happen. But certainly not as much as how women does it. Far as I know, moves like that is a 100% sex invitation in men's mind, which I heard it's not always the true with women?
Men doing humping motion on each other? Everywhere. Too vulgar to be not-joke.

- Upon dating,
'Nice men gets last'
Something that 'nice men' don't understand.


Why?


I have a couple of my own guesses.
One is that women usually comes with passive aggression, and men comes with more direct aggression. Happens to all mammals, apparently.
Two is simply because what we use to see growing up and being uncomfortalbe with anything unknown, probably particulary with intimate ones. Social / cultural education and what not.
Three is the chemicals. Women with pheromones, men with testosterone. I heard the differences are about 10 times. Just about enough to make everything different.

But I'm not quite satisfied with the pieces of puzzle I got. How exactly did these things cause those actions? Or have I missed something?
Or maybe I figured out all the answers I need while writing this down and just couldn't piece them together because I was suppose to be asleep 5 hours ago.

Anyone got anything else to add?
