The first and most important piece of advice is, don't listen to anything DVTimes says because he is clueless when it comes to website design (or anything really).
Second - as others say, your header takes up far too much space on desktop and mobile. You are forcing users to scroll down before they see any content - this is bad UX. Look at what your competition does and do that.
Third. Each box only has four links in it before it fades out. This is too few. You're not getting enough content on the page which gives the impression there's not much there of interest. A box with 10 links in it shouldn't really need a scrollbar. The text above the lists should scroll up with the list, it should not be fixed in place because it's unnecessary from the user point of view.
Fourth. Arrange your categories in the order they are most likely to be of interest to visitors, to get the best bounce rate. I would put free porn tubes closer to the top and move VR porn down.
Fifth....nah, that's enough free advice for now
