I think the design is very good. My only criticism is that its not immediately clear what the site IS exactly. At first it does look like a blog, but there's a membership, which is off-putting. You've got to study the site to see what its all about and most surfers just dive in and then straight out again without bothering.
I think I'd put something in the heading as well as 'Where adults come to play' to describe what the site is. Free Porn Directory or Free Porn Portal or something.
Cheers
