Some money boys play the long game, I see this in Bali A LOT (used to see it in Thailand years ago). In the end they get more than if they were getting a daily fee, the feeling of being "loved" plays with hearts and wallets... and in the end, they end up with gifts, trips, great restaurants and in the end, doing less work (sex).
Or maybe he likes you.... let us know how it ends or if later requests for money show up.
