exposing? outing?

so i’m gonna just ask this question and probably delete it once i get my answer but i was on discord with a master and im in my chastity cage that just arrived today and i was excited and i sent him photos of me in it. i never gave my face or anything but when i wouldn’t do something crossing a limit he said i was a “fake” and i was going to be “exposed”. he then sent me photos of myself. he dmmed me on reddit to start so there’s a good chance he’ll somehow see this. someone tell me it’s all going to be okay so i can go to sleep. i am in the closet and to everyone in my life’s knowledge im fully straight i want to remain in the closet. I have a lot of anxiety about this whole situation and i love my new cage it makes me really happy but i just don’t know what to do.
