There is someone from other country that keeps on blackmailing me about my nudes, and I said that If you still have those nude photos of mine, you don't need to ask for it again. Then he showed me one picture. And he said that if I won't keep on sexting with him he'll post it on the internet. by the way, I dont showed my face on those photos but I have a picture on my account. And it doesn't even have my real name. I know i'm dumb. But please any advice?
