Over the years, I contacted (in Thai) several boys who work in gay porn on their gay online dating or social media accounts. But with slow reply or not getting to the point, we didn't even come to the point "how much". In most cases I probably didn't even chat with the boy himself, but with someone who manages him and others.

There is a very negative trend in Thai language gay online dating (which has a large part of prostitution), in my opinion, which is away from providing sexual services in person to offering only cam sex (usually they ask for 300 or even 500 THB), or not even that, just selling pictures or videos, or membership in gay porn groups on social media. Those who would meet often ask for an advance payment of 500 THB to cover travel expenses. Keep in mind that many profiles are fake, I wouldn't send anyone money. And it's advisable to have a video chat early on to make sure you are talking to the boy in picture.
