Who are they? What is it they do that attracts women?
from my own experience observing them and the women they attract (including me, of course!) these guys are:
1. hardly aware they are charming. they don't even try.
2. simple, childlike, emotionally open
3. real. no pretentions.
4. have both male and female friends. the female friends joke with them a lot--a sign that they are comfortable with them (a.k.a happy being with their company)
agree? care to add to the list?
