Maybe, if you're comfortable, you could wear a pride pin or keep any other form of LGBTQ+ merch on you so that it's always there as a sort of a reminder but not too extravagant. Other than that, you could casually "come out" by mentioning it in a conversation if it ever comes up, considering a lot of your friends are also queer, I'm assuming it's safe for you to do so. It may be a little awkward or scary initially but you are surrounded by people that are familiar with it so hopefully that helps you feel better once it does happen, I'm sure however you decide to approach it, it will go well. If you decide not to go through with it, anyone is allowed to keep their personal life private, if it comes up you could always just say you haven't thought about it or it doesn't interest you, it's alright if you don't feel comfortable to reveal such information.
