Scarlett Johansson? I really don't see the appeal, she looks average. No magnetism, but yeah there is something lusty about her maybe. But would you compare her to Grace Kelly and Ingrid Bergman? Or Angelina Jolie? Seriously, men today have no standards. They think every woman is hot, it is annoying lol. Most men are very simple, actually, and that is perhaps good for women! Men usually don't have an eye for beauty. Yeah sure, they think that woman is hot or that girl is cute, but they don't appreciate the little details, they are too indiscriminate.
Elizabeth Taylor got Pluto-Ascendant aspect. Marilyn too. One could of course ask if Pluto makes such a huge impact even with a minor aspect but you say about one-fourth is born with Sun-Pluto. That miight be true, but I'd say that nearly all sex symbols got Sun-Pluto, it is way above average numbers.
Blake Lively is not Plutonic in that sense, but she got SEX APPEAL. She is very sexy. But did you know that she had a plastic surgery??? Her nose was very big before. She was not this superpretty girl in her youth actually. But that doesn't matter, she got the appeal. Hollywood fixed her teeth and nose, and breasts.
Ingrid Bergman was natural - she never did anything to alter her appearance.
But I need to investigate HOW and WHY Pluto sometimes adds that magnetic look. Sun-Pluto is no guarantee for sex appeal but it sure is the best indicator of it.
What do you think of Alexander Skarsgård? I checked his birth chart. He has no Sun-Pluto or Ascendant-Pluto. In my opinion, he is very good looking, nice features, athletic, but, he lacks all sex appeal - but that is my opinion. Eyes looking too troubled, you decide. Here's a picture:
He got Virgo Sun and Ascendant. Venus and Pluto conjunct Mars, but that's it. No other sexual aspects.
