I know it is unlikely.
But when I watch old Amy Lewinsky videos put out by California Wildcats, Video Sports Ltd and Academy, I always felt like she really enjoyed what she was doing. I mean she clearly isn't acting. She badly wants to dominate and sexually destroy her opponent. She does so in nearly every match. I haven't seen an Amy Lewinsky video where she phoned it in.
Can you think of anyone else? Most actresses do this for a living. But some were really good at their jobs and put in a real effort.
It's generally a common misconception that sexfighting is pure fiction or acting.
There are genuinely quite a few women who sexfight as a hobby and the number is constantly increasing. So why shouldn't this also apply to the girls who are in front of the camera?
You also have to keep in mind that there are or have been actresses who have repeatedly performed for sexfighting content. I'm thinking of Charlie Laine, Celeste Star, Jana Cova, Francesca Lé and so on, big names in the erotic industry. I can't imagine you doing that if you don't enjoy it.
At least that's how I assess it.
