Hello fellow NC boy! More comfortable being nude yourself, or seeing nudity? If yourself, just work your way up to it slowly. Being publicly nude is a big jump, so only do what you're comfy with. Try something like a jockstrap first! If you meant others, honestly when I see others being publicly nude like at the nude beach or at the Castro, I treat them the same way in my head as if they're clothed. No extra attention, treat it like a totally normal thing and it'll feel like a totally normal thing :3
