I think there's at least 3 different dimensions here:
1. Comfort vs. Anxiety: how anxious does a particular interaction make you feel.
2. Introversion vs. Extroversion: are you more recharged or more drained by social interaction in general. (anxiety probably causes people to be more drained than they would otherwise - anxious people probably consider themselves more introverted than they actually are)
3. Awkward vs. Fluid: is handling a social situation correctly hard or automatic? (the expectation of being awkward increases anxiety; anxiety may increase awkwardness)
Some extra dimensions:
- Experience level in a given kind of social interaction
- How much social interaction someone "needs" (e.g. they might get recharged by being social, but not need much charging)
