pretty much all weird gender dynamics happen in upper class and posh environments. You won't find women on a farm afraid to get their hands dirty or men afraid to stitch something. People just do the jobs that are necessary. The entire idea that women are too pristine or fragile to do any work is basically an upper class fantasy because no working class household can afford to operate like this.
Whether its the military, manufacturing or agricultural environments, anywhere that's sort of blue collar or practical people aren't obsessed with their differences that much. I grew up in a rural environment and as kids boys would play with girls, as teenagers we'd go skinny dipping, there'd be none of the weird neurotic and insecure interactions I encountered when I went to university. There's entire categories of stereotypes and boxes highly educated and "high status" people invent to separate themselves in, not just along gender lines.
