Does anyone else ever feel insecure about their identity?

I hope this question is okay to post.

CW self invalidation below.

Sometimes I feel like I must be childish for caring about my identity, referring to myself as a man too often and the like... I feel like I should be one of those people that don't care about pronouns or gender at all and it's just like, whatever for them, you know? And that maybe I'm too feminine to be a man and I'm just nonbinary, though I know that's not true... Does anyone else feel this way? Has anyone STOPPED feeling this way?
