Feedback from our members...
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.
As an amateur photographer I find AdultFolio an excellent site when looking for models for shoots. Also, I have attended several very successful themed castings listed by others that I could never have hoped to organise on my own.
