There's a guy on Spanking Tube - profile agoodspankin - who is my favorite male spanker to watch. His videos are mostly light-hearted and he has a nice rapport with the ladies he is spanking. It's not what everyone is looking for (not a really dominant approach) but I really like his work.
I hate the German chap on Girls Boarding School -- he's creepy IMO. But I also don't like spankers who call the spankee stupid or belittle them in that way. I like a spanker who's just doing it for the benefit of the poor misguided spankee who needs to learn a better way forward.
I find a lot of video spankers seem almost bored by the whole exercise.
