You can't talk about the best adult tube porn sites without mentioning Pornhub! It's the largest out of all the porn tube sites in terms of sheer numbers of videos. It would be pointless to list all the categories of porn video you can find on Pornhub because quite simply whatever kind of porn you are after, you can find it there.
Pornhub allows you to register an account so you can share porn videos with others. However, unlike the bad old days when such tube sites were used for illegally sharing copyrighted material, these days Pornhub takes care to ensure that no copyright infringement takes place. That is not to say that it doesn't still happen of course, but don't expect that you can simply upload videos you've downloaded from a paysite as chances are they will be removed.
In fact many of the videos you now find on Pornhub are placed there by arrangement with the paysite owner as a promotional tool. So you can find full length movies, or at least movie clips that are 10 minutes long or more, with the idea that if you enjoyed the movie you may feel encouraged to join the paysite to watch more.
