How do you know whether you are sub or dom or switch?

[samm]

Thanks for your answers everyone

Still some reflection about this

some subs enjoy giving pain under orders from their dom/me (often to third parties.)

I don't see this as the sub being dominant, do you? It is more like: "I'm sorry I hurt you, but my D makes me do it." I don't think this makes the sub feel dominant towards the third person, they are more or less at the same level with the dominant on top of them both.

To get back to how do you know whether you are a sub, dom or switch, I guess experience must tell. Since I only know that I like being tied up and having a girl in control and such, I know that I am submissive, but I am curious whether dominating someone else can be fun too.
