IT is all a matter of communications. Before entering into any level of serious play, there should be a considerable period of talk and exploration so that both parties are well aware of the understandings and expectations of the other person. Labels get thrown around, misused, changed with time and confused by in exact use. To be safe, you have to get behind the common labels and really explore the meanings and understand the concepts from the other persons point of view. Other than the obvious good outcomes that happen from this is the fact that you tend to learn alot about yourself as well as the lifestyle.
