Can you make me feel better about the situation?

I’m 16 and have been exploring a little bit of the world of LGBTQ+. Turns out I feel relatively confident about being demisexual. And while I feel excited to be a part of such a wonderful and accepting community, I can’t help but feel that being part of it is not fair. I can’t help but wonder that my experience will not be as valid as any other individual that struggles to be accepted by society because I know that I am straight and I’m scared that I’ll overshadow those who don’t have the same privilege as I do and are thankful that they have found a place where they can be proud of being themselves even if they are not widely accepted by others. I’m just scared that I’ll take up space in a place where being a member of it is the most important thing that they use to identify themselves, and that I would make them feel like I am judging them because I don’t have to deal with the same stuff they do. I want to be an ally and I want to be a part of it but I feel like I shouldn’t.
