As a caucasian male - I find all males "unattractive"! He he.
I do believe that likes attract, in male / female relationships, including similar or same races. After initial physical attraction, other aspects of each individual comes into play, however, without the initial "sex appeal" , there is no chance of anything more to develop.
I used to find Japanese women of "no appeal" or attraction to me. (in a physical sense ] ..however, after spending a lot more time in Japan and absorbing japanese culture through film and the internet, I find myself rather attracted to the japanese race (female of course!)
Soooooooo - how about this theory - I understand , and have witnessed, that in Japan, women are the more adventurous in regard to travel - especially visiting other countries - perhaps with this exposure, they, just as I have experienced, are the ones to become involved in relationships outside their own race.?
I do agree with the male and female role theories too...however, thought Id put this one in - It's probably a load of hoo ha, and not really that important issue.....
Jaane.
