It certainly doesn't turn me off, but I don't hear a women say something really intelligent and necessarily find her sexy. An ugly girl with a great intellect is still ugly. She has great qualities about her, but they don't get me wild.

A highly intelligent man or even a man with common sense along with intelligence drives me absolutely WILD, it really and truly does.  As long as the man is not arrogant with his intelligence then that's fine.  I'm not a fan of the pea-brained man.  I cannot even describe to you how mind-numbing it is to be talking to someone who has not got even the remotest clue of what is going on in this world or even worse still themselves.

And the imagination that comes with it.....

A little grey matter surely helps - no one wants empty-headed bimbo...

May not be a "turn on" so to speak, so much as being a dumbass is a turnoff.

Intelligence is sexy; nothing like a guy who can challenge me (as long as he's not cocky about it).
