I think it's at least unwise to classify human gender categories by ethnicity. Also "dating" concept is rather new, if we are talking from historical point of view. Take me, for example. My "dating" experience is no more than several months. But I happily married for more than 12 years already and have two beautiful kids from that marriage. So, as for me I can't tell much stories about my "dating" experience just because I don't have one.
