when it comes to this topic, "sex" "gender" "male" "female" "man" "woman" etc etc are overloaded with contradictory meanings by people trying to make sneaky ontological arguments. unless I'm specifically talking about the signifier itself, I don't really care about these kinds of games, so I just try to say unambiguous things

anyway aside from language legerdemain, the word "sex" is also used to refer to what sex you're legally designated as, which is only loosely coupled to biology by now
