Technoman:
It's interesting to me what words someone uses to describe their size or their partner's size.
For a size with more adipose tissue, one can say fat, overweight, chubby, thick, plus size, etc.
Obese would he a unique choice to use, if accurate.
Does anyone use the word "obese" to describe themselves or their partner ?
I call my partner morbidly obese in the bedroom. It makes him horny when I do that.
Outside of that? No. I don't refer to his size my, but when I do, I'll either refer to him as a "big guy" or "extra fluffy." This is because if I am too blunt, other people will take that as disrespecting him or being displeased with how he looks.
