Why go get a trashy woman, when you've got a beautiful, hardworking and intelligent woman sitting around waiting on you? I feel that most men are intimidated by a female that could possibly be a threat to their own ego.Self image and self worth are very precious commodities in the human race.I guess most of the times and it's normal for every person to be a bit shy at first but I don't call it intimidated.I'm not that bad but I'll say, confident enough to carry a good conversation.
When a man looks at her, he is immediately attracted to her. But a regular or shy man may be scared as hell to even approach her.
Female engineers I know can hold their own with the best but often don't know about World History or Literature.
So, no, smart women aren't intimidating to intelligent men.
It is very easy to threaten these characteristics in the male species.
It is nurture versus nature, a male is predisposed to be the gatherer/ hunter and he is taught that the female is just the opposite.
