No, it does not. The following makes no claims about male fantasy or porn; it is merely a means of explaining that you have made an incorrect inference.
Imagine if you will that, hypothetically, 10% of male fantasy is about humiliating women. Imagine also, hypothetically, that all porn is based on that 10%. In this way, you can see that it is possible for all porn to be about humiliating women, but that does not imply that the majority of male fantasy is about that.
Put another way, if all cows are black, it does not mean that everything black is a cow. If all porn is based on a male fantasy, it does not mean that all male fantasy is represented in porn.
That would seem like a way to escape the conclusion, but wouldn't it make most sense to talk about the porn that is consumed by most men? I'd assume at least 95% of men consume porn (random guess), so my conclusion would still be valid.
