For the record, I'm AMAB and I have conformed to identifying as a man for most of my life. I don't hate being male, and I don't feel that I've had any explicit showing of gender dysphoria, but at the same time in recent times I've also...really frequently thought of the idea that I might be at least some form of transfemme. Maybe genderfluid, maybe full on trans girl, maybe nonbinary with a femme lean...I don't know.
But it's really not easy to come to a conclusion. It's a constant loop of self-doubt and so forth. Every time I think I might be a girl I end up doubting myself in some way or another. Like is this just a weird fantasy that I want to be and I'm not actually trans? Am I "good enough" to really be a trans girl? Am I faking being trans? And so forth.
I've also thought of the idea that I might be genderfluid in some form, though that said...that's to a lesser extent than I have entertained the thought of outright being a girl. I have mostly thought that because I don't really hate being a man and have been okay with it...at least I believe I have.
I am a bit late but hi, wanted to reply to this one as a trans woman bc I remember having similar doubts and talking to a trans woman back then helped me a lot, so I hope it helps you too, at least a little:
There is no quota to meet to be trans. No minimum requirement of transition, of "feminine" things, of feelings. I am a trans woman that still uses he and they pronouns (and the equivalent in portuguese), who still participates in masculine roles (I am butch, and tend to play with masc indentities a lot), who still dresses with masculine clothes, etc. Despite it all, I truly am a trans woman. I love being trans, I love being a woman. Sure, most people don't get it, they think it's weird, but why care? Gender isn't a performance that people are there to judge you on, it's personal and yours. If you feel like a trans girl, well, why not experiment?
You don't have to go all in. Dip your toes in, do what you like, but felt inadequate about. You don't have to have a conclusion now, or ever. You can change your mind, you can create something new for yourself. The most important thing is to find a version of yourself you love, you're comfortable with, you can tolerate. Whatever your goal is.
Whatever you do, however you transition (if you do. You can be trans and not change anything about yourself), people will be there for you. If you need help, advice, or whatever, even if you decide you're not a trans girl, do lmk. I've been there, it can be scary but it's so worth it, no matter the result
