Earlier quoted context omitted.
As a heterosexual female, Matt Bomer is the height of peak male attractiveness. I'd say Charlize Theron would be tops for females. Pewdiepie - ha. I actually find him repulsive, but you are right it's the personality - too loud, too awkward, too ... zany. I think I'd find that offputting in a female as well.
Interesting, Theron is certainly an example of someone whose attractiveness I've mostly heard affirmed by people not sexually attracted to women - there seem to be a fair number of people who possess what we might call beauty without much in the way of sex appeal. What's strange is how unconsciously we'll imagine that someone is highly desired without ever encountering a reality check.
As I get older the more I come to terms with the most attractive women being those who Hollywood never tried to push on me: slightly thick, introverted, and grumpy.
