I tried to scam a sugar daddy when I realised that I can put myself in danger

Obviously the title is self explanatory, but I needed £20 and for jokes I was like "hell why not just get a one time sugar daddy" started with obvious bots messaging me. Whatever, then a genuine guy messaged me however I thought they just gave money when asked. Oh no, this dude wanted pics. Used a random porn stars whatever and he took it. He never gave me any money because he asked for a vid. Just as I was about to send a vid I realised, what's stopping him from just hiring a hitman and taking me out if he finds out the pics werent mine. Blocked him immediately. I suffer from anxiety so yes this idea was stupid however I just realised this now. What happens from then on?
