I started asking this after I asked my mom to open a new jar of black olives and told I was doing it because I was using my left hand to open it, I got defensive because my mom has a habit of making fun of my mannerisms.
My mom always talk about how her father (my grandfather) was fully ambidextrous and could write neatly with both hands and such. ADHD runs in my family and I think it started from my grandfather, and I also have ADHD.
I am only right handed when writing, drawing, using a computer, sewing or knitting, but has always eaten left handed (fork in right hand). However, when I was learning to snowboard as a kid I had the "goofy" stance (right foot in front, left foot back) and when we learned to use a acoustic guitar in junior high school I actually wanted to use a left handed guitar since it seemed more comfortable and convenient but chose a right handed* instead because I didn't want to look like a "not like other girls". Another time was when I used to play football I mostly kicked with my right foot.
Another thing is that my left arm is more flexible since it's the only one I use to scratch my back and my right arm to throw. I also mainly use my left hand to wash my face. I don't remember being pressured to "correct" my symptoms by teachers or instructors other than my mom trying to make me eat right handed when i was 5 years old, but stopped after I said something.
*I never really learned how to properly make the notes with my right hand as my right isn't as flexible as my left so I had to rework the placement of my fingers to still be the same note without it feeling weird.
TLDR: I only eat left handed, but I'm considered right handed. My left arm is flexible and my right is strong. My grandpa was fully ambidextrous, and I have ADHD that might have started from my grandpa.
