I mean im not sure. My wife is a woman and has no desire to be with woman but when young was kinda a tom boy and does not go for a lot of girly things but will sorta girly it up for a purpose. she is a lot like a guy who if they have to will wear the full suit or tux. Dresses and makeup and fashion and such is like that for her. She can do it and even knows how to do it well but does not want to do it day to day. Same with all sorts of other things. I hate cars but she loves them so she drives if we are together. She is far more sexually agressive than I mostly because by nature im kinda an introvert and she kinda likes that. Like the challenge. Its hard to say with like fixing and maintenance stuff. Im a bit more techy and have this thing with shapes and organization but she is more an artist and is just much better than I when it comes to fixing things. Its like I am more likely to be able to do an ugly fix or workaround but she is much more likely to do something where you you had someone else check it out they would be impressed. Anyway we are older and for us there is not real difference between gender and sex. Thats distinction was just no there. When someone said man they meant male and when someone said women they meant female. Medical science could do some stuff but its such a small percentage its not on anyones radar. So I don’t think of her as non binary and she does not think of me as nonbinary. Shes a woman and im a man but we often joke on how im very yin male and she is a very yang women.
