Nope. There are animals with more than two gamete sizes. Egg and sperm are not sizes.

Arctic foxes and fruit flies. And before responding, be sure to educate yourself on the difference between what constitutes size and "egg and sperm". Those are entirely different concepts.

You're confusing sex and Polymorphism. Those aren't different sexes

You're confusing size and type. You can have two types with more than two sizes of a thing.

Look, I'll be direct. You are ignorant. You should fix that. This will help:

"Male" and "female" in biology refer to gamete type (males make relatively small, motile gametes — sperm; females make relatively large, nutrient-rich gametes — eggs). The presence of different sperm sizes or extreme sperm variation in species like Drosophila is variation within the male gamete-producing sex, not a category that removes the fundamental distinction that males produce sperm and females produce eggs.
