I love these questions because they prod at my autism and I can write at length, so I'll just keep it simple. For me, the rating scale is flawed. We all know that. But how do I rate a man or a woman? I rate them based on the physical features they have that the opposite sex finds sexually and physically attractive. Also keep in mind that even within leagues, say in a league of unattractive women, that one ugly woman is more physically and sexually attractive than another (a fat, round-face woman with a big ass and boobs is more attractive than a fat, round-faced woman with no ass and boobs).
I rate a woman on the following: the hourglass figure, which is the base and essence of femininity--her wide, curved hips tapering down and away from her small waist; her ass size and roundness of butt cheeks or ass cheek real estate and the height of her butt crack; the beauty and aesthetic of her vagina (SIMP vagina); the size of her boobs and how aesthetic the nipples and areolas are; the length of the neck and the beauty and symmetry of the face.
A woman who checks off on all or most of these receive a high rating. A 5/10 woman is a woman who is average: so weak hourglass figure, almost unnoticeable; an average and shapeless ass, small boobs or flat chest, average face, and so on.
What makes a man attractive? Tallness, large dick, broad shoulders, strong arms, narrow waist and narrow hips, body hair. Defined face--masculine face, brows, jawline. Not the male model types that incels point to. Attractive men are so much rarer than attractive women based on my extensive real life observations.
Basically, averageness means (to me) people who lack the more "exaggerated" features which put them in the realm of physical and sexual attractiveness, that sets them apart from most others.
For me, Victoria's Secret models are physically and sexually unattractive. I don't see them as sexual beings at all and never will. They are totally pretty to look at but I have no sexual desire for them whatsoever. People have tastes. I NEED a woman like this to get sexually aroused or like this
