A very good Q.My own view is that it can never work.
A client and an escort come from two different worlds
Its not much different from a patient - doctor relationship.
I think if a client sees an escort alot it could mean that the
client is particularily comfortable with this girl and that in it
self should'nt mean he is falling for her.Whereas, the client
may love the thrill of it all, especially having sex with in
many cases a younger woman, few if any will be prepared
to step out of their world and into hers permanently.
