Hey there @mr-aaron :)
Thank you for stopping by. I like the explanation you proposed very much. And I think this is something that stems from evolutionary processes. It is truly down to us to learn to live peacefully with our differences as males and females. I suppose. Learning to do this and being aware of what to expect can truly go a long way when it comes to the well-being of a couple :)
I wish you and your girlfriend a wonderful weekend!
