I think this sums it up quite precisely..
Certain escorts do date clients. They are only human after all. But I except most would keep it quiet. One doesn't want to send out the wrong signals to the punterhood. But I have witnessed posters here and on other forums state that they would not visit Escort A because it is rumoured she is dating Punter B. I just fail to see the reasoning for this is all. I would suggest that the reasoning is perhaps the regular client may feel less special then he thought he was, and would not visit again. Or perhaps punter A dislikes punter B, which is a stupid reason IMO.
But, I have often stated my belief, that "there is no such thing as free sex". But some would weigh up the scenario t and feel the arrangement financially or satisfactorily suits them. Calculation can go both ways mind...
Now THAT is their own business....
