Being among the male specie, I can safely say that I understand the way the masculine mind works and, I must admit, not all of us behave in honorable manner all the time. Before any of you men start screaming at me, let me clarify: I do "not" mean to say that all men are bad, but none of us can deny that there are rotten apples in our lot. (We are all flawed--some more than others.)Having said that, I'll be the bastard that brings out the unpleasant aspect of dating a client. (It’s not pleasant to discuss, but I think it deserves some attention.)
Some clients might take advantage of escorts that are relatively inexperienced; they may date these girls, for whom they have no sincere romantic feelings, simply to get what they want free of charge. (I am, of course, referring to the sort of date that does not require monetary compensation.) This could be tough--even for an escort. It is tougher if she truely has feelings for this dishonest client. Heartbreak is never easy. How does an escort avoid getting hurt by a dishonest client who pretends to be the knight in shining armor (but who, in reality, is simply there for the "ride")?
And yes, I am fully aware that there are other cases in which the scenario is reversed: with an escort dating and draining (in more than one way) a wealthy client she doesn’t truly love. Those who are interested in this scenerio may start a new thread somewhere; I am not rich enough to attract a gold-digging lover so I won’t address it here. 
Just curious.
