Lol at the term "conventionally".
How does it work, is there an organization like the French Academy that decides "this is attractive, this is not"?!
Hollywood celebrities that are supposed to be conventionally attractive never do much for me.
Attractiveness is determined on feedback, if a lot of women let you put your penis inside of them, chances are you are attractive.
Since guys will f*** any decent girl, a woman attractiveness will be determined by how many men are willing to commit to a long-term relationship with them.
The rest is just mental masturbation, leave these discussions to the sluthaters.
"No square jaw! Not attractive! I'm sure he's incel!"
