To follow TGs argument logically would mean that it is wrong to even exchange photographs with a sub or Dom because that would “prove” that you are as you have described yourself. Presumably this would then move beyond the visual aspect to any “proof”, for instance if you received something written by the sub that is in the public domain.
I am seriously impressed if TG has never asked for, or been sent, a photograph or anything else that could be taken as some form of proof that an on-line partner is the person he thinks they are. If, on the other hand, he has ever received any proof at all of an ‘on-line’ person’s existence, how is that different from a web cam, except in degree.
Trust is essential in an on-line relationship, and the trust shown by a sub who will use a web cam is huge, particularly when that cam is a one way street. I do not need proof of anything my sub is doing – like TG I assume it will be done, but to assume that there is NO trust merely because a sub is prepared to use a cam is not only illogical, it is just WRONG. It is also entirely incorrect to assume that a web cam is merely there to show a performance or to see tasks that are being carried out.
As TG admits that he has never used a cam with a sub, I would suggest that he tries it before criticising those who do. That might be give him a more balanced view of the topic before suggesting that a relationship between people he does not know contains no trust.
