Not sure why you didn't just leave the original post gender neutral so that everyone could talk about their favorite male and female tops and bottoms.

I don't watch spanking videos (I prefer to read than watch), but I follow a number of spanking models' blogs. My favorites would be Adele Haze and Pandora Blake, for much the same reasons (they're both extremely wry and articulate writers, perceptive social critics, creative personalities, and living proof that porn stars aren't just too dumb to do anything else).
Both of them have been in a lot of videos on Pandora's new-ish site, "Dreams of Spanking." If I did watch spanking videos, this would probably be my favorite place to get them. Its basically a group of polyamorous kinksters who are all at least friends in real life doing what they love on camera.
Both of them have written articles for the Wellred Weekly, I believe.
