With the upfront disclaimer that I am no web design expert, here are my thoughts:

I like the simple look of the site and the book graphic. Too many sites are cookie cutter porn images and this one has almost a craiglist feel.

I'm not quite sure what the site is about though. I understand the key product is sex stories but the front page kinda loses me, especially the "Being Gay Is" list. It seems off-message. Maybe a line in larger types that says "The world's best original all-gay sex stories...updated weekly"

My eye doesn't know where to go on the page. It seems the info in the left column is really key but it's a smaller size than the column on the right.

I'd suggest sticking with a single font family for text.

You've got some nice galleries...I'd promote more "Free Porn" up front.

Hope the site really scores for you!
