I suppose you might look around some more, find the videos that come closest to what you like, and contact the producer to say you want in. If you are a Free-Market. They are more concerned with whether their particular tastes in terms of race, body type, fetish, etc. are met. The profitability of movies and magazines depends to a great extent on the size of the potential audience. If the audience is too small, high production costs may not be justified.
Women are more likely, for instance, to read erotic stories, while men buy the picture books.
In any case, I know that porn companies recognize a difference in taste and try to exploit it. But my observation is that there seem to be many different companies producing sexual material. And, as I noted earlier, even amateur videos appear on the shelves of adult video stores. If most of them aren't looking for high production quality, then there's not likely to be much. That lowers the average cost over time.
