Hi, guys. It's Larry/Jay. 15FtM(??). Ever since I was around 8, I wanted to do what the boys did and hang out with them. Sadly, I even went through a "girls stink" phase and my role models were my dad and male heroes. I liked it when I saw clothes that were for boys and I got super happy when my hair was cut short because I'd look like a boy. However, I was sheltered from LGBTQ stuff, so I just thought I was a tomboy.
The gender dysphoria never truly went away. When I was 11, I had another "role model", a male character. I wanted to wear a hoodie to hide my long hair and chest and "embody" his male spirit. I even wanted to be called a "he" sometimes. I stopped telling anyone and felt bad about it though when my at the time friend laughed at me.
13, I started experimenting with FtM identity because I never felt fully female like at all, and I always wanted to be like male characters I saw and identified more with them and saw myself AS them. Detransitioned or "desisted" when my girlfriend started bullying guys and especially trans guys.
On-and-off, I've been trans and from what I remember, usually being called "she" or a "girl", triggered me to start acting fem again.
But even with my family, even identifying as a girl, I feel like a boy and I felt dysphoria by being called "she".
I don't even know if I'm truly genderfluid or just FtM due to this since it seems from what I remember, I go back to being a girl due to force or feeling unaccepted.
Labels exist to help you express your identity, not to define who you are. You have plenty of time to experiment, try out new labels and see if you think they fit. And if they don't seem to fit, that's okay too.
