I've noticed it is sometimes difficult or impossible to find a woman intelligent and sexy at the same time. For instance I was talking to a barmaid I thought was stunning, when I found out she was studying ecomonics at university I instantly forgot about her.

The first thing that comes to mind is I am threatened by them, feel inferior and want to be the dominant male, but I generally find only dominant women attractive.

I was thinking it might be a primitive brain (sexuality) versus frontal cortex (intelligence) issue, perhaps these are incompatable parts of the brain, that can't work together at the same time. Like trying to look at both sides of a coin at the same time.

Any thoughts, aside from the predictable phoney pick up line "I find intelligent women sexy"
