From the golden age: Seka! From more recent films: Jersey Jaxin. To be fair though, I don't like the typical porn modern star- they all look like something from a Barbie doll factory to me. With the amount of plastic they have in them they may as well be dolls!
I tend to watch porn for the cocks, so it makes no difference to me who the girl is- I'm more likely to pick a movie because it has Shane Diesel, Mandingo, Lexington Steele, John Holmes, Ron Jeremy in it, so I guess I'm a tad too gay to reply here, but what the hell!
