First, let's define introversion.

psychology : the state of or tendency toward being predominantly concerned with and obtaining gratification from one's own mental life : a personality trait or style characterized by a preference for or orientation to one's own thoughts and feelings (Merriam Webster)

The above is familiar to many who view themselves as "social butterflies" or who don't relate to "social anxiety." My point here is that introversion isn't defined as being "non-sociable."

That said, there are widely observed correlative traits (overlap) that tend to be more commonly possessed amongst those who are Extroverted vs. those who are Introverted. Remember, this is correlation, not causation. And remember, these are relative differences, not absolutes, so they don't apply to all Extroverts or all Introverts. Many people are something in between -- \raises hand**

Here's a table of those other traits from ResearchGate:

Extraversion:

- Talkative

- Sociable

- Outgoing

- Lively

- Optimist

- Touchy

- Active

- Assertive

Introversion:

- Quiet

- Reserved

- Shy

- Silent

- Passive

- Reliable

- Calm

- Rigid

Wrt introversion, based on my observations from PPD at least, I'll add in "neurotic" and "high-inhib" to the observably associated traits as well.

There is no value-judgment in this OP on whether Extroversion or Introversion are "good" or "bad." I'm sure many find full-on Extroverts annoying or enjoyable and many find full-on Introverts annoying or enjoyable.

That said, when we are discussing what women tend to find arousing in a male mate, it does seem to be that it's more of the traits commonly found in Extroverts. A lot of those traits are also traits commonly associated with what the masses tend to define as "masculine." (BTW "masculine" and "feminine" to me is best defined as "traits the one sex tends to find most attractive in the opposite sex.")

Men who are Introverted and who also over-index on those other traits in that list, would do well to work on tempering those traits and practicing some of the traits in the Extro list. This isn't me saying they should "change their core personality," but rather it's me being pragmatic about how they will best attract a wider pool of women.
