This depends on the country. These articles cover Asia only. So there will be no discussion of Europe or South America. But across the Pacific, there are certain differences by nation. In Japan, Korea, and Singapore few young women in their 20s or 30s will respond to western men twenty or thirty years older. A woman of 25 is likely to set her maximum acceptable age for a man at 40, perhaps 45. She is apt to be more comfortable with a man within no more than ten years of her age.
It is far different in Thailand, China, and the Philippines.
In these countries, it is not uncommon for a woman in her twenties to accept a man in his sixties. It is less common in China, more so in Thailand and the Philippines. This writer at the age of 65 experienced the love of a gorgeous young girl of 22 in Shanghai. Without question she would have married me. I returned to Shanghai to see her a second time and was impressed that she would not allow me to spend money on her. She just wanted to be with me. Though I left and decided not to pursue Yan Ping further, I have thought about her often since and wondered “what it?”
One reason girls of Thailand and the Philippines respond to older men is that they seek security. They live in poverty and want to be taken care of. They also appreciate a man who will help support their family – not with thousands of dollars, but with food and perhaps help with the rent. But in return for that security, it is part of their cultural instinct and training to really take care of their man. When you visit Thailand, and especially the Philippines, it is common to see western men in their 60s and 70s accompanied by young women of 22 to 25 or so.
When you first read the profiles of Thai and filipina girls on Internet dating sites, you will be surprised to see how many of them say that age is not important. They will say that “heart” is the most important quality they seek in a man.
