I doubt you'll find many people anywhere willing to talk about doing those activities because they're extremely illegal. As far as this site, I can't speak for everyone, but I think it's safe to assume that the majority here aren't into doing actual harm. I've heard, though, that there's a fetish group in South Carolina, maybe, that's into very extreme play, like sewing lips shut, nailing, etc. I can't remember where I heard about it and don't know if it really exists. Good luck in your search, though I'm not sure I want you to find what you're looking for....
