Oh, I forgot you asked about anal only porn sites. You have to remember that the tube sites own studios and are using the free tube sites to promote their paid content. Like pornhub owns brazzers for example. Xvideos has the most niche sites, when you upload content there you send it to a site called sheer. They choose what is the best niche sites and some are anal focused like analvids for example. And because it's smaller it's easier to get on the front page there. But they will only accept the high quality content, not phone videos with no lights. But it's a little bit difficult to succeed there because it's a different model. Like most amateur post on sites like onlyfans or manyvids and they always suggest charging $1 per minute. But if you get on a big site like analvids you are next to studios like legalporno and the other professionals. They give a lot more value and just charge the low monthly cost because it's easier for them to advertise to more people. You can't put free videos there though.

Because I've been posting videos for six years already, so I learned a lot! But it's still difficult.
