If you want to know if it is truly possible to truly love an escort for who she is, then you must ask the questions:
a) in how far do you know who she really is?
b) what is true love?
In general, an escort tells lies. I don't want to offend anyone, but the nature of the business requires you to lie. It can be about your age, your name, your land of origin to making up whole parts of your life, for those clients who want to know what kind of person is behind the escort. I'm not saying anyone here does, but I can imagine you do.
And the sweet, little things she tells you, that gives you the feeling she only tells you, what kind of guarantee do you have that she doesn't tell anyone else the exact same thing? Maybe she said those things half an hour before your visit, you don't know, and you will never know. So, in a sense, you will maybe never truly know the escort in question. What is the truth, what are the lies? With a good escort who knows what she's doing, you will never know.
Then, what is true love? This is different for everyone. Love is, however, always conditional: you have a series of criteria in mind that your ideal mate should possess. This happens on a subconscious level, meaning that you cannot control that. Escorts probably meet a lot of men that match their criteria, and vice versa, but then you use your conscious mind which action to take. Most will ignore it, deny it, but that works against them sooner or later.
For me, true love is loving the person with everything you have, the happiness and wellbeing of that person matters more than my own. If I would fall in love with an escort however (which can always happen, no one is made of stone), I would want her to have her own choice: continuing her work or leaving it. If she is smart, she doesn't leave on my or anyone's request, she leaves the business for herself, not for anyone else.
So that means she would continue her work. And therein lies the problem: I, personally, think I would not mind her sleeping with so many men, that is her work, just like my work is to lie to people on the phone, sometimes pissing them off for my own amusement. You have to see her work and who she is separately. It's not what you do that defines automatically who you are. I think I would have more problems with her telling other men what she tells me, I don't know what she does during appointments and maybe she would fall in love with someone else, leaving me behind broken hearted.
I use 'I think' because I don't know, and I can only suggest what it would be like. I'll get back to you when I have experienced it firsthand.
