Dancing or more than that?

Sunanda sends her dancing girls 2 outside men 4 outing.Is it ustan outing or is prostitution happening there?Then was Guman also that sort of a woman?But when Samud spent a night 2gether Guman told desai family that she just danced 2 entertain others,but Kumiud crossed her limit n made her body impure.I'm confused.So does that mean that Guman was pure?
