Prostitutes and Escorts don't need to 'be on the street' much anymore.
Most in Australia use 'online' sites.
Ever get that skanky (fake blonde hair, heaps of make-up, heaps of photos of herself) chick try to friend you on FaceBook. The only 'friends' she seems to have are blokes.
A lot of these women work for 'scammers' too. The Russians are the best at it, especially here in Australia.
For awhile, major Hotels were using Hookers via 'dating Agencies' to lure a guy in for sex. He would have to pay for the cost of the room of course. Probably still happens. I joined a 'major' Dating Agency many years ago - more out of bored curiousity (because I never really got 'actually involved'), there were many women I could tell, who were more than willing to 'milk my money' via avenues for sex.
I feel sorry for guys who get sucked into this. Sure, there were the 'sincere' women who were looking for long term love, etc.
I've also worked as a Nude Model. Sure, I did it for the money. But having a slight Art background. I enjoyed the challenge of providing for would be up and coming Artists.
Of course, there was the usual problem when one 'Director' is Gay and the stigma that all male nude models should be 'Gay'.
