Let's all be real here.
Cash is an aphrodisiac for women. It makes them feel safe. This is not just the case with K-girls or A-girls, it is a universal. But there are some exceptions, girls who truly dig character over everything else or the package over everything else. This happens particularly after girls get burned time after time with "bad boy" types and high rollers who can attract hotties like candy attracts files. They start wanting someone who is cool, funny, and caring- a completely different kind of safe. Smarts, humor, character, reserved confidence are the other aphrodisiacs. I know this because right now- I find that I have attract more women than I ever have in my life, a lot of women in their late 20's and early 30's because they are thinking about the whole package because they are thinking about getting married.
Working girls are definitely trying to do their best to survive. I can imagine this has to be one of the most difficult relationships between a man and a woman who have who grown up where monogamy is the norm. It must be hard if your girl has to work, not just for the jealousy factor but from the male provider instinct factor. If you had enough benjamins you could free her from the situation, but because you don't she has to work. That must suck so bad.
I think if you want the fantasy pay a visit to your favorite MP, if you want a relationship, it must not be about sex, it must be deeper and chances are probably better if the girl is retired or you can make retirement possible. But what are you falling for, looks? Are you truly compatible? Why do you want to enter what is probably one of the most heart wrenching relationships possible?
I would say if you want to play it safe just visit the girls for play. If you have the poise and a good reason, a K-girl can be as good as any girl.
Last point. I was talking with a friend who was dating an MD PhD, nice and eligible, mom would approve. She is completely neurotic and bitchy, daily discord is the norm. Spoiled from the get go, a life without bumpy roads, everything came so easily, ego through the roof for all the accolades, total fucking bitch or nut job. I heard so many stories like this. I think to myself, forget the fucking labels and look at the person. One of these girls can be some of the nicest people you ever met in your life, just because she was in a desperate circumstance once in her life doesn't mean jack shit. In fact adversity like that can either make a person bitter or wiser,kinder, understanding, sweet, and more appreciative but not without scars. Find the latter girl and you could have a lifetime of bliss but you better be mature, cool, smart, and patient or you are going to melt down when you hit the rough patches.
Just my thoughts.... Everyone has their own experience and opinion.
