I'm assuming you are using already existing (and legal) content, scraped from the web and compiled into an "adult tube" format? The reality is that you are jumping into probably one of the most saturated markets in the world. If you truly wish to set yourself apart, you need unique content - end of story.
Most folks use the "reupload method" whereby you quite literally reupload existing adult videos with your watermark, URL or voiceover implemented into the media itself. You will get traffic from such methods, but it will be minimal and sustaining it over a long period will be tough due to large platforms actively removing your altered content very quickly.
If you're looking to make money from adult content, unless you have the experience, know-how or unique content that will sell; move on. There are easier ways to make money.
