Not really. Concepts behind gender conformity didn't start becoming a thing until relatively recently in human history. And even then, gender conformity has always been fluid (the man didn't always wear pants, the women didn't always have the most elaborate gowns, the high heel used to be considered masculine, the wig and makeup used to be seen as gender neutral.) Fitting things into a binary was something we came up with and we haven't always been able to keep up with that.
