HELP MY CONFUSION PLS

I am going to be super honest here, so pls be nice I just need help...

I already came out as gay, but still dont know if I am gay.

I am very confused, because some days I feel gayer than the others. Sure, there is no question that the only crushes I have had so far were girls, which led me to conclude I am gay, but accepting that did not give me any sort of “liberation” or “eureka” moment I was expecting. I just kinda accepted it in a nonchalant way. It may sound ridiculous, but I kinda fear that my exposure to LGBTQ media in my early teens led to believe that I am gay, since this happened to a friend of mine who now identifies back as straight. I really dont want this to be the case because it would be devastating now that I came out.

Any advice?? What assures you that you are gay and how do you not question it?
