Well, gee, Wontworry, I hope you'll let someone else play!
I think slavelucy has put this pretty well, and, like andibabe, I have a little experience in this line.
About this time last year I began a three month on-line relationship. Photos were exchanged (which don't mean a damn thing because they're so easily copied from the internet). Orders were given and, supposedly, followed. Stories were written.
In the end, it turned out that both of us were lying (about different things). If I ever get in another on-line relationship, there will certainly be a web-cam or some other means of verification involved. Lack of trust? Oh, yeah! Big time lack of trust. Having been both biter and bitten, I am at least twice shy.
This crosses over into three or four other threads, but considering how most BDSM players look (me included), I just can't see using a webcam as a turn-on. Who wants to see that? I certainly wouldn't want anyone else seeing me! I guess it's like rubbernecking at a car crash.
Whatever floats your boat.
