... that there's no trust in your relationship?

Why else would you have to prove that you are carrying out his orders? If I gave an order, I would assume it was done. On the other hand, most of the times when I give an order, the submissive gets writer's cramp.

In my entire time online, I have never had a webcam. Internet messengers and the telephone was all my submissives and I ever needed.

In online relationship, I prefer to work out the mental aspects, because the physical can come when I am physically with the person to whom I am speaking online. Besides, an internet relationship is the perfect grounds to get to know your partner far beyond the 'how far can you put your legs behind your head?' barrier. Internet relationships give people the opportunity to provide and complete writing assignments, questionnaires, summaries, book reports and more. Online relationships are perfect for discussions through forums, chats and messengers about relevant topics, and not just ones related to BDSM.

In essence what I am saying is that there's so much more to do with an online relationship than watch someone 'perform' or carry out tasks on a webcam. Unless, of course, your relationships differ from mine and all you want is just a pure, sexual and physical aspect to it. Which is fine, too, if you don't plan to ever meet in real life.
