I was very curious and wondering which aspects/placements everybody in the community considered to endow people with physical beauty or sexual magnetism. Or on a more general level at least how particular configurations affect how we look and the image we identify with. Perhaps planets in the first house? What if they are in first but not in ascendant sign? Any specifically gorgeous aspects? Placements? All feedback is appreciated

I will post a link to my own chart for reference.

Honestly I know you've heard this a million times but when it comes to sexual magnetism, scorpio wins everytime. This comes from my observation of the world. I view the world around me and observe what "good looking" guys actually has lasting effects on women. You'll find looks whereever you go-if libra, taurus, leo, aries and pisces(especially women) take care of themselves, they'll be attractive. But scorpio men have a lasting effect. You'll care what he thinks, you'll ponder over what he says and feel upset when he's not paying attention. It's also like subconciously, people know that they have an abundance amount of passion, so when they are ignored by the scorpio they feel like they are not worthy or even worthless.
I've also met a woman who has venus conjunct pluto, sun and mars on scorpio. (I grew up with her) She's not badlooking. Shes just not very pretty. Interestingly, enough she never was popular with the boys growing up but she'd be obsessed or fixated on a guy every now and then. She moved away. I believe she's dating a guy right now. She's way more successful than any book smart person who she grew up with. And if you stalk her instagram account, you'll see how artistic she is. She's confident about her body, her make up is on point, she dances, she draws, she travels and you can simply tell how passionate about life she is. She lives life to the fullest and she is an activist. I would be surprised if she wasn't popular with the boys now.
The thing is with scorpios is that they have an amazing desire nature. Sometimes it comes through and people can subconciously recognize as something they need(especially other plutonians) and they get hooked.
Aesthetically beautiful is all about venus and perhaps neptune.
Venus Conjunct Ascendent being the top
Venus conjunct Neptune
Venus in hard aspect or trine to ascendent
Then moon, ascendent, sun in libra, or taurus.
Give more points if you have ascendent, sun or moon in the first decan of taurus(bharani lunar mansion-this lunar mansion is ruled by venus but surprisingly also rules the 8th house)
So bharani natives are sexy as they get.
Also Give points if you have sun, moon, ascendent in purvashada located in capricorn. (another venus ruled nakshatra-moon here is especially prevelent for victoria secret models.)
I think just scorpio will give beauty to some extent because it is a sex sign(it will perhaps not make you below average).
