Hello, Doctor. Good to see you again
I don't know if this applies to new feedees as a whole, but I've been spending some time on Tumblr (which I eventually discovered is riddled with teenagers), and follow a lot of feedist blogs. What I've noticed is that the younger feedees/feeders/gainers are much more confident in their fetish and decide to gain weight much earlier/younger than those of us who didn't have the internet as we know it during puberty.
I think the normalising effect social media has really helps them overcome the social pressures that prevent people from gaining. That and, since the majority of them are American, they're growing up in the fattest nation we've ever seen, which also allows being fat to be less abnormal than it may have been for some of us older folk.
I imagine that if I'd stumbled across feedism early in my adolescence, instead of at 19 like I did, that by the time I got to college and away from home I'd be chomping at the bit to fatten myself up! FF and feedist communities are so important in providing me a sense of normalcy that I'm almost sure I would have arrived at my current point (happily fat and getting fatter) much faster if my world then had looked like theirs today.
Kids these days have it so easy!
