I'm so confused from what I just learned in biology. I'm 14 by the way.
Both of my parents are biological females. But I'm a boy. How is that possible? If my dad donated XX chromosomes to my mom who also has XX chromosomes, why do I have XY?

Theoretically I should have XX, regardless of which of the Xs was fertilizing.
Where did the Y come from, and are they my real parents?
