I didn't get hit with real extreme dysphoria until I became a teenager. And even then, I identified as non-binary for awhile because I didn't hate my body so much I was suicidal or anything. I have been depressed for a really long time - I'd say deeply since I was 13 or 14, but the really pahological need for love and approval started way before that. It sounds cheesy, but my parents got divorced and my mom got a boyfriend immediately after, and some of my earliest memories are feeling neglected and stuff. I've always been awkward and chubby also, so boys never really liked me. But when I broke up worh my first boyfriend, I got really depressed and even more needy. I had a tumblr, and felt a lot more confident online because I had a lot of friends and stuff, and it was easier to talk to boys. There were two boys off of there I sent naked pictures to (and by naked I mean topless and/or my butt with just my underwear on), mostly out of this need to be distracted and feel loved and attractive. And then I met a boy on omegle who was real sweet and we would talk and he was into crossdressing so he'd send me pictures and stuff, and we never made anything official and actually dropped the idea of calling each other boyfriend and girlfriend, but we basically dated for about five months. He lived in the UK so it was hard to talk sometimes but he was always kind and sweet and called me mistress. And I liked it, I liked all that, I liked using my body in that way, or being a girl, or something....
But then the dysphoria came back. It was really bad when I was 14, and then I ignored it, and now it's back. But I question if I am "really trans" since I had those experiences. But then I think depression and emotional dysfunction are really intense, you know? So maybe it is possible the need to feel cute was stronger than the need to be a cute boy. I don't know.
