Great posts, all! And it makes me recall what I've learned in stateside action: attitude is everything.
If you see each other as someone you would have enjoyed meeting in a bar or other situation, and go back to someone's place for fun, it turns out pretty much the same. The money is just the set-up for the meeting, and if you keep it from being a big deal, the fun goes on just fine.
I came to think of the money as sort of a "retainer" for a certain skilled group of attractive women who have reserved a portion of their lives for us. The "downside" is we don't get to think of ourselves as uniquely attractive to her, and we may not think too seriousily of cutting her out of the herd for our very own -- we'd be messing up her livelihood!
(Or, like we're the male and female members of a very privileged club, and we only deserve its benefits if we mutually follow the rules and best practices that the club has developed to enjoy its hobby.)
Unless the chemistry is very right AND you can make her a better offer, then you might as well just enjoy the moment and the memory. It's been worth it for me, in its time and place.
The hardening or wearing down? Well, it takes a certain segment of women to embark upon this with any regularity, and also to find their own exit point, a very solitary commitment, I imagine. Many do not handle it well, but it is possible and many do. Planning a long-range financial future is something most 20-somethings just don't do -- anywhere.
The business of being a courtesan goes back thousands of years, and it carries the penalty of deferring marriage and family, and the risk of never achieving them, but the wise and lucky woman can pull it off just like any other, and maybe do even better overall.
But as dapanz says so well, it is a high-stakes game for them, and many spin out of control.
To walk into a lower-income country and enjoy a session with a new-met friend requires respect, a light-hearted attitude, and appreciation. I've done that, and hit at least 70-30 with partners who responded well to me. Certainly didn't feel like either of us was sliding downhill on those occasions. (I worried about a few of the others, but not for very long

)
