It depends for me. Naturaly, being an introvert, i'm attracted to extroverts. ha ha I remember when I first "fall in love" ( almost ): it was an extroverted girl, a very extroverted one. I was looking at her and literaly absorbing everything what she was doing: her playfulness, outgoingness, and also her openess to almost everyone.
But, on the other hand, many extroverts tend to be very shallow, and in a strong relationship, there is not place for something like that. Hoewer, I've met many extroverts who are very serious people, in the sense that they search for meaning in life, they take a relationship very seriously, they are responsible, they understand what it means to enter into a relationship. Those are some basics values that I expect from a extroverted girl. If she's a child that wants to have fun all the time, or party or something like that, that's not for me, at all.
Introverts are ok for me if they've got some social skills developed. I met some introverted girls wich were very attractive.
Regardless of what I just said, I thing typology isn't a deciding factor.It is really the person !
