Hello princess!
During a conversation with some friends or family, you will speak about the sissy fetish. You don’t need to say you’re a sissy. But you will tell them you heard about this “weird stuff”. You must sound amused and disgusted. Wait for their reaction and see where it goes.
P.S) Bonus point for you if you manage to conclude something like
Well, it’s an harmless fetish. They can do whatever they want.
