sorry to say, but what a load of pish. Only insecure and shallow men feel intimidated by intelligent, fabulous women in a higher position. brains is beautiful but of course a lot of people (men) prefer dirty talk over an intelligent conversation anytime.
Intelligence doesn't fade, beauty does over time (or it evolves if you prefer) so I would take that with a bag of salt.
for all that its worth, you are a very brave woman that is confident where she wants to go and what she wants to achieve. if that is not sexy for a man, then he is probably not even worth your time.
Sorry to be so blunt, but been there, done that.
I dream of the day that I can finally fill in the second eye on my daruma..
