This thread is not hurting for contributions, but I will post anyway...
I thought about this question for a long time and realized that I had a babysitter from 4-6 years old that was cute, chubby and kind of alt. We used to watch MTV and cartoons together while eating popcorn. I definitely had a crush on "Ann Marie".
Several of the kind, pleasant, non-old teachers were chubby. By contrast, all of the skinny teachers were mean, skinny hags. In Preschool, it was Ms. Tina. In first grade, it was Ms. Carcich. In second grade, it was Ms. Ossie. Shout out to all of the big ladies that showed me love!
For most of high school, I was into mid-size, chubby girls but not any of the true BBWs. Then the first girl that I ever kissed was 5'3" and nicely over 200 lbs. She had pillowy, huge G-Cups and used to drape them up and down my body. After that, I was hooked!!
The first online BBW that I was into was Mandy Majestic, back when content creators were called "webmistresses". I'm a dinosaur though, so I remember dial-up internet with very few BBW models.
