Yes that is their job description and they are not allowed to advertise that they do sexual things and are also not obliged to have sex with the client but don't kid yourself that the majority of them don't have sex with their clients. Old blokes are not throwing thousands of dollars at them just to hang off their arm at a function and showering them with gifts without a little something in return.Escorts do things like go out with men to be seen with them in public so people can think they've got it all. Basically, their main target are older rich men. They are just people who act as your date/partner and dress very sexually. Sex isn't really meant to be involved though. Sex workers are prostitutes.
