Well to be honest. In medieval times boys were allowed to do everything like learning to read (if noble) go have fighting lessons, calculating lessons, go fishing/ survival. engage with plenty others, just name it and boys were allowed to.
Girls on the other hand were meant to help with cleaning, knitting, doing household stuff and being a good wife, not learning fighting skills or reading or calculating. Just all the things to keep the family happy and well fed.. This caused that most of the woman had only minor roles in history until the 1600-1700 except for a few exceptions
However I can understand that a lot of the political correct folks and the currently sensative people all around the Western world can't accept this, So for the games sake I wouldn't mind of girls in medieval times being just as good in everything like the boys are... (I mean biological muscles/strength, womans menstruation, laws and local traditions from those times all don't affect anything,, can all be thrown in a trashcan because we now wish it for it to not happen.
