You have picked up an interesting niche to create a website on. You still need to work on the content and it is all about quality over the quantity, so it is better to have 100 videos with unique titles than to have 1000 copied videos without any change.
Also, you do not need such long descriptions. You could write around 30 up to 50 words and it is the best length in my opinion and 180 words is an overkill for a tube to be honest.
I have to tell you that the logo does not look well at all and that blue font is barely visible on the dark background. For most of my niche sites I just use the text name and honestly logo makes a difference if you are running a popular tube like PornHub but for small stuff is not that important. Make sure that you have a sitemap built and there are plugins to do this and I have shared many other SEO tips for tubes on this forum, you can find them using the search feature and if you can not get anything useful, I might give you some links later on.
