Coming out

Hi, I'm 13 and gay. I originally came out to my 3 closest friends as bi, but now I realize I'm gay. I sort of want to tell them I was wrong, but I think it would be awkward (I also have a crush on my friend and told her😳). Also, I want to come out to my parents, and I know they would be supportive, but I don't really get the point of it, since I probably won't have a girlfriend until I'm much older. Help!
