This case has nothing to do with sex, gender, gametes, chromosomes, fashion or any of the assorted guff - it has to do with compelled speech. You may very well have a preferred pronoun and you may request that other people refer to you using said preferred pronoun, but ultimately how people call you is not up to you, it's up to them. In the United States the state is legally prohibited from compelling speech on the basis of the first amendment which protects the right to free speech *as well as* the right not to speak in a given manner. If someone wants to refer to you as a "he" or a "she", that's their right, even if you consider this classification to be incorrect - you can't coerce them to do otherwise. If they're doing it on purpose to cause you grief, they're being an asshole, but that's not illegal. If you don't like this kind of communication, you should remove yourself from the situation and exercise your freedom of association by not associating yourself with people who are assholes to you. If said person refuses to leave you alone, there are anti-harassment laws on the books already - get a restraining order, stalking is illegal. You already have all the power in this scenario and are adequately protected, I see no reason to use the long, strong arm of the government to force people to speak a certain way that you subjectively find agreeable.
