Your posts are making two common mistakes that I see a lot when people comment on foreign women:

1. Assuming that a foreign woman living in the US/Canada is similar to foreign women in their native country. This is almost never the case. Picking up a Greek woman in the US is always going to be a very different experience from picking up a Greek woman in Greece.
2. Taking experience from 1-2 random women you once knew and extrapolating assumptions about millions of people based on their personalities. That's like saying, "I knew a short girl once who gave good head, so I imagine all short girls probably give good head."

If you've ever been to Roosh's Travel Forum, threads there are rife with both of these types of posts and all in all, no real useful information is ever shared. In fact, sometimes you just promote inaccurate beliefs or stereotypes about women or a culture you don't actually have any experience with.
