Adultfolio is the best site I know in the area of provocative, candid photography to porn art. The features are all very well thought out and the art presented is mostly very good.

Been working with this site for a long time now.
As an upcomming photographer it's not always easy to get noticed.
Adultfolio definitly provides the means to do so.
There are alot of amateurs around and it shows in the quality of certain images, there are tons of high level quality shots going from portrait to porn art.
Keep up the good work!
