I have been a member of AdultFolio from the start. I find I get more work through this site than the others as they allow people to see exactly what you do and not just cover it with the term Adult.
I've been on AdultFolio for quite some years now and have to say I've never had a bad face to face encounter yet. The ability to check profiles and references means I feel safer and understand what the photographer needs and is trying to create. Overall I use the site a lot and rate it highly.
