I don't think desires are created from nothing. Exposure can amplify things. Somebody with an interest in dubious consent could move towards ever more violent nonconsent in their porn choices via its availability. In a much less extreme way, we do see changes in people's real life choices regarding sex acts being influenced by pornography as these sex acts have become more accessible in porn (choking, anal sex, and facials are commonly cited). This suggests that porn is changing behavior rather than simply responding to preexisting desires.
