Of the thirty or so gay men I've had contact with in Korea, it might be revealing to take a look at the statistics.

Men I've actually met in person: 13
Men I've had some sort of sexual contact with: 7
Men I've had some sort of satisfying sexual contact with: 2
Men I've had sexual contact with more than once: 1
Totally into me, but not attractive for one reason or another: 2
I'm totally into them, but not attracted to me for one reason or another: 2
Mutually unattracted: 2
Language barrier makes it impossible to tell who is attracted to whom: 1
Men I've had to travel to another city to meet: 11
Number of other cities in Korea I've traveled to just to meet a man: 4
Men who have traveled to my city to meet me: 1
Some kind of spark, but not worth the travel: 3
"Oh, did I forget to mention that I have a boyfriend already?": 5
"Oh, I have a boyfriend, but let's fuck anyway": 3
Super sweet, and kind of attractive, so still a contender: 1
Dates set up for this week: 2 (not counting today's--see "boyfriend", above)

Not terrible odds, I guess. Still, a pretty inefficient market. Currently a bit discouraged. If these guys later this week don't pan out, I'll lay off for a while--but I always say that . . .
