Something tells me this Q&A applies to lots of women (and with a little transposition, many men, too)...
Most important, your intelligence can be an advantage. You can use it to be funny, to ask questions which show a man you're interested, and to subtly flatter him.
The problem is, you've convinced yourself that flirting is distasteful. It goes against your self image. You may be like so many women in my seminars and workshops who are also bright and opinionated. Unfortunately, their firmest opinion is, "I'm not going to stoop so low as to flirt."
It's almost as if you and these women are challenging men to instantly find and love the "real" you. When that happens, your intelligence turns against you, and what comes across to guys is a hostile, "I don't need you" attitude.
Wise up. Flirting is fun. It's a biological imperative, part of the mating ritual of our species. Refusing to flirt is like being the only peacock who won't spread his feathers, and then complaining because the female peacocks ignore him.
Sure, you might find a guy someday who will push his way through your "I don't care enough to flirt" attitude, but why wait?
Another reason men and women both refuse to flirt is the old, "if I don't try, I can't fail." Just remember, if you don't try, you can't succeed, either.
Flirting is not a betrayal of your intelligence or feminism
or anything else. It's just a way of letting a guy know, "Hey, I think
you're interesting." Since guys have to make almost all the first moves,
a little flirting on your part gives them the confidence to approach you.
