I have a close trans friend as well as a co-worker and I would say just do whatever you were doing before, but this time trans. Sure, you’ll have to have “the talk” with your friends to ensure they’re cool, but being trans doesn’t change your personality or interests. You’re still the same person at your core, you’re just living your truer self. So if you liked playing d&d before, keep doing that. If you like gaming, keep gaming.
