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.
If photography is your hobby, then AdultFolio is a fantastic resource and well worth the membership fee. I only shoot a few times a year, but I know I can find reliable professional models to ensure the studio days are a fantastic success.
