Did I do it right

So I had this 20 year old guy text me and I’m 14 so I said bye and he was like send a selfie and even though I’m a single Pringle I said no I have a boyfriend so no and he said fine then I’ll just send you cum shot videos and said then I’ll just block you and he said no you won’t so I said watch me and blocked him. Is that ok? Or should I have done it differently
