Asians!

He goes by «Boss Asadayut» (sometime also spelled «Assadayut»).
While he does some explicit modeling for a few Thai photographers, I don't believe he has any adult-oriented social media himself. The only personal account of him that I know is his Instagram Page and that is mostly focused on his work as a Fitness Coach.
Apparently he did do some porn, lots more info in this thread Labourbbk Onlyfans (thai Guys)
