🤦‍♂️ Biological sex.

Gender reveals make about as much sense as a sexuality reveal. They're creepy, gross, harmful, and often just outright incorrect.

You'd be better off doing a "this is a picture of my fetus's current genitalia with an ultrasound". At least that would be demonstrably correct since it's a current picture.

Like... Even assuming gender magically works the way these people think it works, who gives a fuck, and why are you so fucking annoying about it? Plus, I wouldn't want random people to see my genit- Oh wait a second...

Oh god .... Oh no...
