I was talking to a girl from Omegle and she asked to talk on Telegram and we talked there and she told me to send my picture and I send her a picture for other guy not mine the picture was normal no nudity or sexual things, She sent me her nude pictures, so I did not continue and blocked her, she only have my phone number so I found her talking to me on WhatsApp and saying this. I made a block immediately as she did not continue, and it passed more than 10 hours and nothing happened at all. I removed my number from all my accounts and disabled the accounts. Is this dangerous or not?
she send me the same picture I have sent plus a male organ next to it and I'm really scared
