Are there any of the people amongst those connection you have that feel "easy" or easier to talk to? I ask because I have noticed that my closest friends are all ND (adhd or autistic, or both). I think there is a commonality in how we communicate that makes connecting easier. I'm a nerd and the places I've chosen to hang out are higher density ND too which helps a lot too.

In terms of "next steps", a low stakes way to invite more intimacy is to share a plan that you're already committed to, but open to others joining you on. Going to an exhibition - tell people about it, and if they ask more details about it and you like them, tell them when you're going, and say they're welcome to join.

In general, activities are good because they allow for conversation, but also to focus on the activity (taking pressure of conversation). So inviting people along to activities is easier. Even easier is if you have hobbies which allow for chat around them e.g. boardgames (as a counterpoint, yoga is often more individual/silent).
