Very interesting Topic :-). Online Play involves a huge amount of trust as it is so easy it is to portray yourself as basically anything you want on the internet.

I believe online domination or playing has a role, although no amount of typing will ever replace your senses, online play is an excellent way to explore aspects of your own sensuality.

I do not know what it is about "being online" but experience has told me that people will reveal considerable more about themselves in chat than they will face to face.
