Master and the Sub

Only being on here a short time I have made many wonderful friends all with kind words and the same problems we all seem to have. Which is good it shows were all human and life is better with friends. What I have also gather from some conversations and it being posted on profiles is how many Dom's think you can just start demanding someone to be your submissive. My past Sub was already train to a degree, but we spent long conversations about many topics and went back to have talks about more things before it was agreed by both sides what we both enjoyed from the relationship. I do know there are those that want and enjoy that kind of arrangement but please have the curtsy to ask first before assuming every sub is the same. Just my opinion I'm sure some will have different thought's these are just mine.
