I’ve been in the lifestyle for more than ten years. Before I began exploring, I was almost always the dominant partner in my relationships. Now, I am thoroughly enjoying my submissive side. I was surprised to discover that there is nothing quite like the pleasure felt when you realize that you have pleased your top. I am a Switch but tend to enjoy the sub side a bit more.
I am not a masochist.
I definitely have a little girl side and enjoy the daddy Dom style. I actually wasn't aware of my little side until about 5 years ago. I thought everyone was like this - sparkles, faeries, unicorns, rainbows, etc. My little/middle is between 12 and 16. This does not include age play. I consider age play to be role playing.
Another definition of alpha sub has to do with poly relationships. It refers to the most important sub in a Don’s life. It’s the sub who gets first priority.
