I don’t think people know I’m pan…

So during COVID I came out to my close family and friends but my friends (2 people) and brother are the only ones that know that I am pansexual. I’m also really shy so it’s hard to talk or get to know people. I also don’t  think that people think that I’m not straight. That was a confusing sentence. But I think I come off to other people as straight. Like I want to be in a non heteronormative relationship but how do I hint to other people that I’m not straight. I’m also polyamorous but I don’t really know how that would work for someone like me. I’ve never meet another openly poly teen.
