The moment of actual realization must've been around 6th grade
Had some swimming courses at that time for a few weeks as part of PE
So obviously all the girls weren't "hidden" behind your everyday clothes wearing swim suits or less
While all the boys were talking about their favorites I noticed I felt different
I didn't like the skinny girls, I liked the two fatties in my class
One being a chubby pear and one being a, quite fat for a 6th grader, single belly girl
I loved the belly, the rolls, the jiggling everywhere with every move
I loved when we got on the bus, how nothing happened when everybody got in
But when those two got in, that thing was shaking noticeably
That was my first actual moment of realization that it's fat girls for me
It was just there from the very beginning, like hardwired and coded
The moment I started being interested in the opposite gender, it was fat girls right away
And that time was when I realized it
The bellied girl was totally into me all the time, but I was to shy and dumb to realize btw xD
