I am, too, and have given up to get it straightened out. They are just definitions and there are probably as many definitions as there are kinksters.
I'd say that if you have to act, you probably are on the wrong path. Apart from that: Nope, there's only one right way and that is your way. Don't let anyone tell you that you're not a true slave/sub/Dom/whatever if you don't do this or don't like that.
You don't have to figure it all out. Well, maybe you do, but you certainly don't need to hurry. Take it easy, take it slow and most important: Be safe and have fun!
