I've been wondering about this recently.
In a little over two years (God willing!) I will graduate from medical school with my MD. I'm also a rather tall and athletic woman so I wonder if men are intimidated by this combination. I am attracted to men who are passionate and motivated in their field of work and I probably fall into Victor's former category... I care very little about the degree that a man has achieved. I find other qualities in men to be so much more attractive to me! However, in some cases a higher degree (or lack thereof) is an indication of underlying motivation (again, or lack thereof). I want to make this point very clear: Passion and motivation are very attractive qualities regardless of whether they coexist with a higher degree.
I think I can understand that many men may have a preference for "greater stature" than the woman that they date or marry. I don't want to underplay this dynamic because I do believe that it's important for a relationship to enhance and highlight the God-given masculinity and femininity of the man and woman respectively.
I have more thoughts on the subject, but they are currently not quite coherent so I will quit while I'm ahead.
