好吧,这么久了,只有这么几个姐妹赏脸回复,我想也有另外些兄弟姐妹想看回复,下面我就给个别人(美国人)的回复,也算给其他感兴趣的人一个答复

I think that most men only flirt with girls that they like, though in Western culture, many young men like lots of girls. :)
I advise all of my Chinese girl friends to stay away from young western men before the age of 25-27. They are not bad, but I think Chinese girls won't understand their thinking.
Relationships in the West are often like this.. a man shows interest in a woman, if a woman likes him, they will start to date (which of course includes sex) if they like each other, they will continue dating, maybe not and they break up. Western women are much more 开放 about sex than Chinese girls.
For relationship, I would stay away from handsome young men, they just want to play. Find a nice older man, maybe in his 30s who likes China, and wants to live in China. Then your chances are best.
