I had no luck on tinder when I was in Thailand and the Philippines. Thankfully I went to those countries just to get surgery, if I went thinking it would be easy to get women I would have been sorely disappointed. I only really matched with prostitutes/scammers. I did match with an obese single mom in manila who was a few years older than I was at the time. She even agreed to meet but flaked out on me and ghosted me.
That was a decade ago too. These days it's even harder in those countries because you have tons of young, decent looking guys going to SEA specifically because they think it will be tutorial island for them. Now you have literal chads like Austin Wayne and HTNs like Aesthetics Waiting who live in Thailand. Another case of neijuan.
From what I've seen, sub5s who went overseas generally only "dated" prostitutes. I have no interest in that sort of thing though, never did.
No country for sub5 men.
