Gender is a social construct you know. Liking pink, wearing dresses, makeup, all of that is because of the patriarchy and how society created these norms. Having boobs doesn't make you a woman either.

But you know, when a guy becomes trans he will wear dresses and get boobs.

Totally makes sense right?

Also don't forget there are infinite genders but whenever somebody is trans they only go to man or woman. But there definitely isn't just 2 genders guys.
