I highly recommend Adultfolio to photographers and models, for one main reason the interaction there is between photographers and models that doesn't exist in other similar sites. Here I have found incredible models with which we created amazing photos thanks to them.

AdultFolio is an excellent resource for finding models, simple to use with high quality images across the site. The two way reference between photographer and model also is not only pleasing to have it also acts so we know what to expect on our shoots.
