re: Dating advice: is dating a ‘dumb’ girl sustainable?

In my opinion, hell no. Over my lifetime I've had a few women come and go that I considered nothing more than "frick-buddies" and most of them were what many would consider dumb.

Sex will only take you so far and sooner or later there needs to be other stimulus in a relationship to keep it going. To me, nothing's worse than trying to talk to someone who is clueless about most things.
