I think you have a little too much advertising on each of the pages - and in a lot of cases, the ads don't match the page your on - take the ebony page for example:
http://www.xxx-adults.net/ebony.html
Why have the 60 links in the table on top there when 58 of them do not fit the category?
I'd shit can all of those tables & replace them with a banner or 2 that is specific to the niche page that the surfer is on.
Also, on the main page -
http://www.xxx-adults.net/main.html - the tables look off - the text looked centered in itself, but then they are all left aligned - just looks off to me
