This is a great explanation of how to tell people about your therianthropy! Personally I won't be telling my family until I move out to my own house just in case, and also so that if they don't accept me I won't have to live with the feeling of being judged.
If you do want to tell people, it's a good idea to think about what their reaction will be, so that you can have the highest chance of acceptance. I know that my parents won't take it seriously and will tell me it's a phase, and might even try and get me therapy.
Using the method of guessing people's reactions, I have only gotten acceptance so far! I've told my great friend who was nothing but accepting, they love asking me about it and plan to sign up to TG to learn more! I told two other friends who just kinda accepted me but forgot about it the next day
I don't mind though because they were still nice about it.
But that's enough about me, this is kind of a bump post lol. If you think someone will have a negative reaction, refrain from telling them!
Remember that you don't have to tell people about it. But if you do choose to, good luck!
