Cam "reverting" back
I don't know Cam so I don't know what's really going on with them and I do love to snark but there seems to be a lot of confusion on Cam going back to feminine ways so to hopefully clear up confusion as to why LGBT people tend to do that, speaking only on the ftm trans side of things (personal experience), a lot of people that experience dysphoria, after being on hormones for long enough that you get some permanent changes like voice drop, bottom growth, more body hair and have gotten top surgery become more comfortable with themselves.
So even though Cam is looking feminine again, they still have a flat chest which makes clothing feel completely different and they have the freedom to be shirtless. Even if they look girly, they still have a deeper voice now.
So yes you can look more feminine while still being more comfortable with yourself because now when you talk they hear a deep voice, they see a queer person, they still see some masculinity.
Gender is not all or nothing
