Queer relationships tend to be more fluid because each person is free to be who they are or want to be in the relationship based on their preference rather than predetermined roles defined by society. In a way, they are a social experiment for what relationships could look like where gender is not the most immediate organizing factor, as it often is. When you imagine what it would be like if we assigned roles in relationships based on arbitrary characteristics like hair color or earlobe shape, you see how ridiculous it is that we do it with gender.
