Frank,
To each his own. There is a major attitude difference that would preclude me ever visiting a Nevada brothel. Just not going to happen. American women have lost sight of some important distinctions between the sexes IMO. This is a generalization and does not apply to all.
The girls in Thailand are typically more upbeat and friendly. On average, they are slender, attractive (by our standards), young (18-25). They want to go out disco, drinking, a movie, or to your room. The difference is using a whore, and renting a girlfriend. It is more like a date than hiring a pro. I can not explain it. My bet is, one trip and you will be returning for life.
However, you will never know until you try. I'm guessing the cost in Nevada can run upwards of $200 an hour. It doesn't take more than a long weekend to blow (no pun intended) $1000 there. For a bit more you can experience something so different as to amaze you. Again, descriptions and pictures will not suffice to explain the experience.
To each his own. Alas, too many of us (Americans) will never make a trip outside our borders to see what the rest of the world has to offer. The only negative to Thailand, IMO, is the length of the flight. It does take a while to get there.
