For me, I wouldn't say it was the first. Think things like "I don't identify as a guy, but I'm technically cis" to "I'm not cis, but I'm not trans either" would be earlier cracks.

maybe! I think I was viewing realizing that you're trans as the very beginning, and thus transition as a development like fetus in an egg. although I don't know what a finish or fully cracked egg looks like in this analogy lol
