watching too many JAV here people. It can get addictive and change perceptions on how girls really act in life. Snap out of it! Western girls, asian girls, malaysian girls, they all act the same around the globe!
Lol.
That sums it pretty well I think...
But I think JAV reflects one part of the female population in japan : the one that exists in japanese men's minds. It seems to me that most japanese guys want their girlfriend to be like submissive and not really aware of what's going on in a bed (or at least let's say that it's one of their big fantasy). Add to this the "lack of overt sexualization in the Japanese culture" that aquamarine was telling about and I guess you got the "pretty and unspoilt" play you find in AV.
But that's because they're giving the mass what the mass wants, really don't think all japanese girls are like this really. Some of them are real sluts. I guess that in the US or in Europe, men are more turned on by slutty girls who know what they want and how to get it so porn back home tends to reflect it.
But it's also true that I met some japanese girls saying "I don't really like sex, it's just to please my boyfriend"...
well after digging (!) a little, you soon realize that's acting too...
