I am really attracted to women with bleach blonde hair.
Oh yeah?  Blonde hair is blonde because it has low levels of the dark pigment eumelanin.
I think it is very hot. Although brunettes are nice too. I am not generally a fan of natural blondes though. Not sure why.
There is a blonde vs brunette rivalry in many countries.
I'm sure there is. I know in Italy there are is a rivalry, but in Argentina many people prefer blondes rather than darker colors.
Yep!  It goes way back to Ancient Greece, where blonde hair was prized and many women tried to lighten their hair with chemicals.
