I find Myanmar, Thai, Lao, Khmer boys more attractive, but I could fulfill my sexual desires in Taiwan if I could get those I like. The problem is that Taiwanese gay guys have little to no interest in me. I have no idea why. Apart from that, Taiwan is a great country to visit.
Economy is irrelevant. I calculate (Boys in my room) / (unit of time) to decide where to go for a gay holiday.
I know you have good luck in Taiwan, I know of others who have good luck, but for me, it doesn't work out. For gay encounters with locals, I go elsewhere.
For me, there is a general trend: Myanmar, Thailand, Cambodia, Lao works well. Vietnam so-so. China, Hong Kong, Taiwan poor.
