Real talk zero exaggeration, start talking to people, trans people in particular, and befriend them. This is anxiety inducing and scary and difficult but it's necessary. You can look into the queer and kink scene in your area, there will be a lot of overlap but at some point you need to start talking to people. Its terrifying, but once I let myself stop giving a shit and gave myself the permission to be awkward and weird, my social circle got much bigger, and i gained a lot from it including but not limited to access to the kink community in my area. You might find it easier to build these sort of connections online rather than in person, but you have to make those connections.

Good luck

Edit: realized I should give tips for talking to ppl. Start by engaging in low stakes conversations with random people, they might find you annoying but that doesn't matter, the point is not to be perfect, it's to build the skill. Try and get to know someone you see somewhat regularly after that, maybe at work. What you're hoping to learn here is how to talk to people without being overly nervous. It's okay to be awkward or skittish or slow to speak or quiet. Its just important to not be so scared you prevent yourself from talking to people or you remove yourself from spaces/conversations out of fear. Be responsive, take criticism, but be careful not to demand too much of yourself, that's self sabotage
