All those things are shared bro. I can and do all these things. But i do get bitched at when she sees me in the sink. Lol I'm told to get out of there. But that aside your asking a very complex question.
Backgrounds, upbringing, culture, societal rank, education, personalities. All these things play a part and no human book could ever contain those complexities. That's life's knowledge.
Personally i just learn the game and try to understand the nature and the biology of this dance and have a good time.
You get to a point were nothing suprises you and not much matters but in a funny way.
