Here’s my theory. And it’s just my take so feel free to disagree or say I’m being an ass.

It is complicated but for a 5/10 dude like me it’s simple. 9-10/10 you are one of the most attractive people I’ve ever seen. 1/10 you make the elephant man wince. 2-3/10 I’d have sex with you if we were really drunk. 4/10 if have sex with you but nothing long term. 5-7/10 marriage material with personality being the qualifier. 8/10 I might get to have sex with you if we were really drunk. Obviously preferences come into play. For me a stick thin woman with protruding cheek bones and perfectly symmetrical features sometimes called a model, is 7/10. A 10/10 would be a curvy (wide hips but not fat) tall woman with big boobs and softer features.

My wife is a 7/10 to me, the sweet spot. My favourite parts of her are her wide hips, flat stomach and her jaw line. I feel like I’m lucky to have sex with her but I don’t feel insecure doing so. But her personality sings to me a 10/10. A lot of relationships are based on two people who subjectively think the other one is more attractive than the average person might perceive them.

For a 1/10 or a 10/10 perspective is completely skewed. To a 1/10 everyone 3-10/10 looks like a 6-10/10. To a 10/10 everyone 1-6/10 appears like 1-3/10. If looks are on a bell curve then some 75%+ of the population is ugly to them.

Now 7/10 are the people you most often talking about how looks don’t matter and personality is all that’s important. Well of course it doesn’t. To them nobody is sexually out of their reach and most people are attractive to them. When every one is fuckable personality becomes extremely important in telling people apart.
