Depends on what you mean by "touch" . Of course an arm around ( for a price ) might be OK, but a happy ending I doubt.
Japan has a sex industry that would blow any of our minds, but the cost is more than most would be willing to pay. If I won Lotto, I might indulge in a once in a lifetime event, but for the rest of my life it would be Thai girls. They may not be particularly adventurous in bed but better than most westerners will ever know.
