I can't give you an honest answer about the reasons why all Western men are attracted to Chinese women. There are as many answers as there are men and women. The whole article is dishonest, provocative and meaningless, and I'm sure totally unrepresentative of even the author's opinion, ignoring the part where he seems to want to speak for all men. "Hey guys, it's not about the sex, it's about man's need for their own space." That's probably a line he uses when he wants to dump his latest conquest. "Babe, it's not you, it's me. You're beautiful, sexy, and subservient, but I need some alone time right now, so zaijian."
He can't co-opt me into his specious, juvenile theorising. Speaking for myself (and I can only do that), my wife understands me like no-one else. It's impossible and pointless for me to escape intimacy with her, emotionally and physically, and why would I? I am exactly where I want to be. It's rather a strange action, don't you think, to travel across the the world to be with someone and then refuse to be close and refuse to share our lives. It's like travelling to the moon, and then saying, "actually, I don't really want to make that step onto the surface." I hope that my wife and I understand each other more, not less, share more, not less.
I suggest that the author has serious intimacy and commitment issues. Perhaps we should leave him alone with his self-justifying fantasies. I think the rest of us are busy learning Chinese, careful to avoid misunderstandings, trying every avenue to communicate with our wives, via webcam, email, EMF, phone, translator and face-toface meetings, so that we can be closer, not farther apart from the women we are not afraid to say that we love.
