Well first of all, no I met these girls. Theres two more I met in real life as well, one a mega sadist. She had cat ears. I said nekomimi she said furry and then we started talking about fetishes and never stopped and before we knew it we had spilled our art accounts to eachother.

Another had a sketchbook full of guro. Actually I've net plenty of girls with monster girl and horror themed sketchbooks and that's always a tell.

Theres a third I met irl never online who was just a college friend, eventually she told me she had some bloody porn she drew but she wasnt willing tonshare it, I was to afraid to tell her how interested I was so that didnt turn into anything.

Gonna recommend fetlife.com again. There, you can just make a profile about how much you wanna be slain. If you get no takers, tweak it to you do. Talk candidly on all it's different threads and forms. People will talk to you when they love your ideas, and when you love someones ideas, you'll have a reason to talk to them.

And as for how to meet show your interest? Well, the way a girl shows me that I can tall to her is:

Chains, collars, corsets
Cat ears or some other weeb paraphernalia that implies they arent interested in being normal
Love of corpse party, goblin slayer
Goth
Choker
TIME. Lots of people seem to have real deep kinks, but they're only gonna let those show to someone who they feel can ACCEPT them, and make them feel good and normal. They dont want do feel even more weird and even more anti social, and feel preyed on by others like them. You risk doing that if you're too up front.

Though I am constantly shouting my ethics about how cartoons are fine fantasy. There are lots of people raised Christian who like yaoi art and stuff, who inherently understand that fantasy is fantast because of that experience, so that's a good way to start talking about it if I feel I need a friend who understands.

But yeah, wear eye liner, wear a handcuff under your work clothes, and go out there and meet some people. It's a numbers game, if you know more people you know more guro fans. So weather its online or irl, once you put the time into your online persona, they'll start appearing.

And it helps to be you genuinely going for your interests and being noticed, or finding people who you like that are reaching got theirs. Or, understanding and appealing to what people want: a friend, a fuck buddy, or a person to date.

If you just want someone to appeal to your interests or bust, and you want to jump straight into knowing and enjoying them from the git, you're looking for a prostitute, or pornography.
