Lindsey Knott's Naughty Space

What is sub space? How does one get there?  Am I not functioning properly because I have never experienced it? These are questions that have been bouncing around in my head for a few weeks.  The Mr. and i have not been completely involved in the D/s world for long. Before we met each of us had admired from afar, but when we met someone who's dark kinky desires matched our own we decided it was time to take a leap. While we are very happy that we started the journey into this lifestyle together, we are running into the problem that neither of us has much experience. We have done so much reading and listening trying to soak it all in and one thing keeps popping up. SUB SPACE.   Could someone PLEASE help me figure out what it is, how to get there, or at least tell me I'm not less of a sub due to my lack of experiences? 

I've been putting a lot of thought into the who, what, where, why, and how of my individual journey into submission. Like was I always this way, or did previous experiences bring me to this lifestyle. After a LOT of thought and contemplation I have come to the decision that it was always in me. I remember as a young girl I always liked being the girl who needed to be rescued from the evil king or kidnapper. Not because I wanted to be a princess, I was far from that. I was a tomboy through and through. I wanted to be that "damsel" because even at a tender age it stirred something in me. It gave me a high that at the time I couldn't explain. Fast forward to the present and my favorite parts of the Ds world involve being bound in some way, shape, or form. The other stuff is hot too, but being bound will always be my favorite kink.
