To each his own, I'm not that attracted to a man with a thick beard, but a man with an extremely low beard and mustache is very sexy. For the record, back hair is not sexy either.
I love a tall, dark handsome man and I recall as a child being attracted to Stanley Baker in "Sodom and Gomorrah" (he had a black goatee) and Jeff Chandler in "Gengis Kahn" (also a black goatee). Currently I like Johnny Depp's facial hair!
