What does it mean when someone identifies as gender fluid?

When someone identifies as gender fluid, it means that their gender identity can change over time. Instead of feeling like they are only male or female, they might feel like a mix of both or something entirely different at different times. For example, one day they might feel more masculine and prefer to express that side, while another day they might feel more feminine. This fluidity can be based on feelings, experiences, or even situations they find themselves in. It's important to respect their identity and understand that everyone experiences gender in their own unique way.
