So i have a good-looking brother who isnt very smart but makes up for it by being attractive, social and confident. Face at least 7/10, body is 8/10, length 6'2.

So when hanging out with him i notice that even tho he isnt smart, smart girls also fall for him. Even when they have nothing in common. This is contrary to my previous believe where i thought smart nerdy girls like smart nerdy guys, and dumb hot girls like dumb hot guys etc. But this isn't the case at all. Its a dumb fantasy made by males.

Guys like hot girls, and girls like hot guys. This thing called "chemistry" is quite simple. The moment a guy is hot enough and can lead a conversation the woman will feel chemistry because her reptilian brain tells her she found a good mate. Of course my brother just has sex with these girls and doesnt make them his GF. We joked about the poor bastards who will go on dates with these girls, all dressed up and nervous, while they sucked my brother off within hours after meeting him. And these girls will eventually pick someone like themselves, someone with similar interests and traits, and that similarity will be the glue for their relationship.

Well, i realize i could very well be that poor bastard. If i meet someone at 30, when my social anxiety dies off (it lessens by a significant amount every year), and i make decent money, i could very well find a girl that thinks i am decent enough then. There is however a significant chance they secretly wants a different guy, because i have seen them chasing my brother like groupies. So when one will eventually pick me, its because she realizes guys like my bro have literally dozens of girls chasing him. So some might pick me for being average with similar interests as them. And i will be grateful like a stupid puppy for having someone who shows interests after 30 years (LOL). This really disgusts me tbh. How do you cope with this? Is it even possible to find a girl who also fails now, but succeeds later by finding me in the same way i will succeed by finding her? You don't have to tell me, i know that is just a sad fantasy.
