I've got a cute virgin chinese girlfriend, i'm good.

You know I considered this actually but I realized that i'd be doing it literally only for validation. Unlike girls in your city, getting hundreds of matches with SEA girls (most of them probably not being interested in you but your supposed money) probably wont lead to sex.
Say you match, what then? You can't plan a date because you're in two different countries, and the culture difference is usually big enough you dont have many hobbies in common. Sure you could schedule to fly over there and meet up some day, but why would you not fly over there first, then use dating apps and not have to commit to a girl? If you dont meet up immediately you need to keep a conversation going and that makes it incredibly hard to talk to more than like 4 girls at a time.
