I don't think it's any actress inparticular it's more of the set-up, position or vocal nature of a scene. I think that's what seperates my porn.
Although a Christy Canyon scene has never disappointed me.
I agree with that completely. Also, I usually watch movies when jacking off rather than pics, but there are some pic sets that work for me. Nina Mercedez and Crissy Moran are two great examples.
