Well I started the post so heres what I think
A TRUE submissive acts on behalf of her Master or awaits her Master's commands.
One who tops from the bottom has pre conceived ideas.
In other words is more interested in getting her rocks off for enjoyment rather then serving or being pleasing for her Master.
This does not make it wrong just different strokes for different people.
I personally would call it kink not D/s and definatly not BDSM.
Just remember it is the Master who has the final say.
