Gender Fluidity and Adding Gender Identity Exploration for Sims

I don't know exactly how this would work. I can pitch a few ideas. Having a select multiple/all for pronouns would definitely help. I don't know how this would work out precisely. One way is giving the player a notification when a sim wants to change. As for gender identity exploration, small interactions like try out different pronouns in the mirror. I am not transgender nor am I a game developer. I am not very good at expressing my thoughts into writing/typing. I just feel that everything shouldn't be because the player wanted it to be.
