We do not get an archive of either side of the show, but we do get an archive of the chat itself.
The pictures would have to be a screen shot. If you don't wish to end up there, don't visit that particular model. Or ask her members- did she ask before doing that?
As to the dick thing... I'm weird. I do get turned on by seeing a dick, but it's not just seeing it that does it. When I see a dick, I start imagining what I'd be doing to/with it if it was my lover's dick. THAT is what turns me on. As soon as I've seen the dick itself, I don't need to keep watching it. (BUT as soon as someone asks me to put what I'm visualizing into words, I go from this mode: visual -> sensation -> horny, to this mode: visual -> words -> disconnect)
BUT I'm plenty happy to play that I like to watch it, since I know that guys like that. In that case, it's not quite a lie, since I like doing what guys want me to do. So I'm turned on by watching it not because it itself turns me on, but because it makes the guy happy.
