No that is just something that Blonde people made up. Brunettes and redheads that have just as much fun. I personally love them all. Men who choose women based on hair and breast are probably sexually and emotionally immature.
Personality shines through to me more than looks to me atleast. I have been with some pretty woman that had the personality of a dead battery and that was no fun. Then again I have had some woman most people would not consider very attractive and had a great time with them.
