Funny thread. Hey, why does almost anyone go anywhere to do anything? (Gee, did you think it was really all about serving the Japanese people with our amazing English skills?) Yeah, some may come to learn Japanese and see another country, but the underlying wish is always to find a sexual partner(s), make money, eat good food and have a good time, and to see how other people live (doing just the same.) No one is unselfish, on either side.
And Japanese girls especially are hardly innocent victims, More like willing partners who lead foreigners on and in, hoping to bargain a better life for themselves with a bit of sweeter-than-heaven tight pussy and don't you want more of this gaijin-boy?--then you'd better marry me and take me away from the nothing life that otherwise awaits me.
How do I know? I was an innocent language teacher in Tokyo, at age 21. About 1/3 of the female students I taught were there for one and only one reason: they wanted to hook up with a gaijin. I was their U.S. representative; they were into me not because of me but because I was American.
I didn't screw them all (though I easily could have) because I really wasn't interested in that--especially the doll-eyed stupid ones. Sometimes I regret not taking what was right there on the table before me and being readily offered--but I only regret it cause I didn't. If I had screwed these morons, just to get some, I would have regretted that too. There would have been ugly entanglements and bad feelings later for those hours of fun. Ultimately not worth it.
Not that I didn't have sex with Japanese girls--just not my students. And I actually stayed with one for a long time, learned Japanese, learned what the country was about and the desperate situation most of these girls were in, which led them to dream about Americans and try to bargain a better life with their long hair and eager pussies as bait.
So, don't be so judgmental before you examine yourself and your own situation. First, just as not every female student was in my classes to hook up with a foreigner, many language teachers come with other motives. And those that come to screw ultimately don't even enjoy themselves all that much (believe me, I've seen more than my share--they've stories in buckets but no truly good experiences.) Because, frankly, most Japanese girls aren't actually there to screw and enjoy good sex--they almost always something more (marriage, security, a life as more than a wife-servant) and the foreign teachers are almost never there to provide that.
If it was just about sex and sexual satisfaction, everyone would go home happy. But it's not. Japanese women wouldn't give it up so readily if they didn't think it would get them something, and when they don't get what they want, they get bitter and call gaijin liars and sleezes and write posts like this one. (Even if it's not for real, you hear this kind of thing being said in Japan all the time.)
