Well, I'm not sure what you mean by "been to uni", though I assume "university".
I might feel a bit uncomfortable in the last situation if she liked to rub it in.
"How about an intelligent girlfriend who has been to uni, obtained several masters degrees and simply puts you to shame when she speaks, again, how would you feel?"
Though I think if I had had assurances that she never meant any ill-will, I'd manage it.
Overall, I'm not exactly a "Macho man" who would be too hurt to think about accepting this situation. Although, with a powerful woman scenario, the hardest part would be the introduction. If it was already established that she was interested, even --and especially-- if it mean being inferior/subordinate to her, that would be the hardest part out of the way right there(in which case, hell yes. Not about to let pride get in the way of a relationship). Otherwise, she might be unapproachable, and the scenario not able to take place, as no one willing to be considered the underdog would have the guts to approach her without external intervention.
