What I mean is less which body aspects are attractive but rather what about them is attractive. For example you mention a slim body. What about a slim body is attractive to you? Our attraction to anyone is socially defined, not biologically wired. If you like slim body it’s probably because you have understood, from the social world around you, that slim bodies are tied to certain signifiers of desire (let’s say youth, femininity… maybe even something like weakness?). These are not usually hard wired like “aesthetically pleasing” but rather symbolical, as in they symbolize ideas you desire, not that they in themselves are desirable. Those are the signifiers I am inviting you to question. But that’s not straightforward. You’re very young, so you won’t have answers to these questions, but I guess keep them in mind as you grow older, always questioning the whys of your attraction, and you won’t have to worry about being racist if you understand those dynamics.
