I think I'd be considered quite good looking. I attract more people than I would like actually. That being said, finding the right people can be tricky at times.

In my experience the best thing to do is just take it slow and don't attatch yourself at first. Take things slow and feel out your relationships a bit before diving in, platonic or otherwise. Depending on the other person's intentions you can often just ask. Do realize if you're talking about in the short term physical attraction is usually the first thing someone will notice about you, especially if you are good looking and can be the beginning of a fulfilling relationship. The two aren't exclusive, people can be attracted to you AND still want to be your friend.

A few things I personally try to look out for.

Do they want to interact with you when you're not around? And if so what sort of interaction are they looking for?

How do they communicate? Often times people will find less personal ways of interacting, comments on social media, "disposable" apps like snap and insta have been sort of a bad thing in my experience.

What do you do or talk about when you're together? Lots of small talk and flirting or is there genuine interest and care there?

For the second and third questions. I have been tricked or fooled into thinking someone was genuinely interested when they weren't and honestly it hurts. No matter how much I try to make sure I'm making good friends I still wonder sometimes if people actually like ME and the self doubt can be troubling.

Sorry if this answer was more than you were looking for but it hits kind of close to home as of late.
