You can find mainstream porn all over every tube on the web. Quality fetish? Not so much.

While there may be a lot more potential buyers or bigger market for mainstream porn, there is also an ocean of that content on every tube site for free. If you have a more mainstream porn itch that needs to be scratched, you can do it fairly easily without spending a dime on a porn membership if you're a traditional adult business model.
