New little

I just started getting into being a little. I've been with my daddy for three years but only recently started calling him daddy and being a little because he wasn't open minded to anything like. Now that he is, he absolutely loves being daddy but I don't know how to go about being an actual little. He doesn't give me rules other than to obey and listen. I need guidance really lol I don't have anyone else to talk to about this because no one I know is into this and will more than likely frown upon it.
