Lots of very insightful responses here for you Shadix. Not sure I can add much but here goes.

Introversion and extroversion are simply ways to describe whether you get your energy internally (inward reflection) or externally (social contact). You can be a sociable introvert (I'm one), which means you like and enjoy company but need your quiet recharge time, extroverts I believe do not need that recharge time. It's not black & white. It's also a spectrum, which means there are degrees of introversion and extroversion and like some people have stated many people fall nearer the middle. You may find it interesting to complete the MBTI questions as the results will measure your introversion/extroversion and give you the percentage, they will also measure other aspects of your personality based on your responses.

Going back to your original question. Some women are introverts attracted to extroverts, some are introverts attracted to introverts, some are extroverts attracted to introverts and extroverts attracted to extroverts. Broadly speaking though introverts and extroverts tend to be attracted to similar to themselves - not always though. Neither is superior or inferior and certainly not the most important thing in who we are - if anyone tries to tell you that then that is simply their own prejudice leaking out, let them keep it.
