Irish-
I think that it is a fair question, and agree with you about hollywood being a little off in their sex symbols. Maybe Leonardo is sexy to teenage girls, not to me. I think it is a jaw line for me, or strong bone structure. Not sure exactly... I like Val Kilmer, Sean Connery, Jean Luke Piccard(can't remember his name), Mel Gibson.
I think younger women like a more feminine look.... or it seems so. I have nothing against the Leonardos' of today, just not my type. I like a man's man!
