Well it’s hard to start a relationship with someone if you don’t ever communicate, so I’d start by opening communication.
If you do successfully open communication, though, I wouldn’t be too surprised if they weren’t interested in someone who considers them to be a “thot” or “shallow instagram girl.” Sure, there are more intellectually stimulating activities than browsing instagram, but I enjoy my memes and those aren’t exactly mind-blowing theses of grand intelligence and profundity.
If you throw money at them they’ll probably talk to you at least some, but you should realize that they’re just doing their job. I don’t think there’s anything wrong with paying for a cute girl to smile at you and make you feel good, especially in these recent times, but if you resent them for being attractive and providing a service that people are willing to pay for, then I suppose that’s your own problem.
Hot girls are in abundance, of every body type, of every sort of personality. If you really want to have sex with them, then just start doing lucid dreaming practices. You can have sex with anyone if you do that. If you want to have sex with hot girls in real life, then it’s only fair that you put in the work to take care of your physique and health just like they do. It’s never “just their metabolism,” it’s a lot of dedication.
Some advice for getting anyone you don’t yet know to talk to you though would be to provide value to them in some way. That’s what people do in business, and these girls are running businesses. Is someone gonna fuck you because of this? Perhaps, but I’d encourage you to instead drop the scarcity mindset and enjoy their presence in your life.
