Brian Williams is neither sexy, nor possessing of a stentorian voice, and appears humorless.
Being a straight male I can't address whether or not he's "sexy" (although he appears to be a handsome man), but on the Today show this morning Williams actually displayed very good sense of humor (including a bit from his appearance on The Tonight Show where he made a crack about Star Jones' wedding and how it must have been a mosh-pit atmosphere at the buffet line)!
He appears to be something of a closet comedian, but simply cannot let it fly during the Nightly News telecast.
