This is an absolute truth
for the person who wrote it.
It definitely has some good points but I personally dont think it holds any absolute truth. I am no sub so I can ofcourse not be completely sure and I can say that my experience with many(2) isnt that extensive to speak with that much athority either.
You (when submissive) or any other sub will have to feel for yourself if all or some of it holds true to you.
edit: bah. I ended up writing what Rhabbi wrote although it was in other words.
