Actually there are many templates that have pretty much the same look as the XVideos but obviously many features are missing. But if you are looking for the WordPress theme for your adult tube site then I can only recommend WP-Script (here is the link). They are honestly the only choice since other shops are not updating their products and are not as good as what the WPS offers. It looks like that Anyxvideos.com is using this very template and good thing about this template is that it is quite fast and it has an optimized code for search engines.
However, if you want to rank your tube then you will need to keep adding new content to it regularly and always make sure that you use your own titles. Another important thing is that it would be easier for you to pick a one niche and focus on it rather than creating another XVideos or other general video porn site. Also, look around this forum and you will find more helpful information and if you have some questions that have not been addressed already then just post them away.
