The second truth, tied to the first, is that many of these girls have grown up in cultures where taking care of the men in their families is almost a genetic predisposition. Like it or not (and personally I do), these women still play the nurturing, supportive role which has been devalued and disowned in so many more "modern" societies.
Now, this is not to say that you're dealing with a poor, weak, defenseless, mousy woman.
first of all, is it really true; and secondly, how do relationships with such age disparities work out in the long run?
I'm a 63 year-old American man, myself, and have lived and dated younger women in more than 10 countries, including the Philippines, Thailand, Vietnam, Mexico, Colombia, and Panama, to name a few.
Younger girls often perceive older foreign men as stable, financially secure candidates who can not only provide security and educational opportunities for them, but often for their families as well.
