After reading the question on female body hair, it occurred to me that the matter of male facial hair is similarly rooted in culture. While there are certainly many women who find male facial hair attractive, it seems that the majority of women prefer their men to be clean-shaven, or at the very least, without a thick beard. Naturally, this plays into what men do (i.e. they shave because they want to be seen as attractive).
Since facial hair is natural on men, however, why don't most women find it attractive? Shouldn't the norm be to find facial hair attractive, and the exception to prefer shaved faces?
