Yes, there is the shown-in-action aspect of stolen or misused shots. I guess I don't get into them as much because they tend to have a big COCK in them. I'm not homophobic, but cocks just don't do it for me.
On a related note, knowing that the girl knows about the nude shots of her makes it more sexy. On the other hand, over the years I've had the privelage of owning nude shots of women that I know but who don't know I have them. That's exciting, too. If I had any of these anymore, I would post them. I've just lost them over the years.
