I think introverts don't necessarily want to feel attractive, they probably feel better about being attractive to others, but it's not something they intentionally seek, In my case, for example, I'm an extrovert and also an assertive type of person, but i'm very low in aggreableness and compasion, and that makes me less extroverted than other extroverts who have high levels of such traits, and one thing I've noticed, is that even though it feels good to have other people's attention, it's not something I look for specifically, for me, it feels like an addition when I do things right, and when I don't have attention, I don't care. And I think that for certain types of individuals with more or less introverted personalities the same thing happens.
