Will wait for the guys' answer on Galadriel, but I think the whole thing about her seeing into everyone's mind would be intimidating for the guys. I bet that is why they don't go for her as much. You have to be kinda slow and brain-empty, like Celeborn, in order to survive such a relationship.
But at least if Galadriel could read their minds, then she would have no excuse for not understanding them!
There is a lot of things about being attracted to a wearer of one of the Rings of Power to be intimidated about. Most guys don't want to end up like the Earl of Leicester, or especially his nephew the Earl of Essex, if you remember Elizabethan history.
Yet, right after passing her "test," (Blanchett as) Galadriel looked shaken, vulnerable, even passionate for a moment. I'm probably one of the few who like Jackson's characterization of her.
