Does anyone have any idea?
depends on how many viewers.. depends on how you allow access..
EG some sites are free to view, but then demand a donation for specific requests/ sexual positions.
some are locked down and have access only after payment.
some are paid purely by advertisments on pages of video's
some women can make $10 a session, sometimes they can make hundreds.. but it all depends on how many viewers you have that are willing to pay. or just being open to free-loaders and hoping someone will be generous or that the viewer count will be enough to grab something from advertisers.
