I thought everyone was very clear about the difference between gender and sex, particularly on this thread. a persons sex is their biological identity. Gender defimes which 'social construct' they identify with.
These constructs are constantly changing. The social construct of being male or female 100 years ago or more was far more rigid than it is now. men were expected to be in charge exercise authority provide for his wife and family. His place was in the world. A woman's place was in the home, the classic 3 ks of the Germans, Kinder, Kerke, Kuche,(children, church and cooking)
Social constructs of gender have changed over the years women work, have careers, share the 3 Ks. I can well see a future where social constructs of gender gradually fade away and, male or femail, you can live, dress, act anyway you like without being labelled as anyone other than yourself. The only limitations, will be those posed by biology.
