General

I've been attracted to big girls my whole life and I've had fantasies about being bigger myself long before I even knew what sex was. So if something 'caused it', it was a subconsious thing in my early childhood. I'm not a fan of those psycho-theories though, what's wrong with just being born with a preference for the curvy side of life?

Like all fetishes, feederism is triggered by early life experience. Being overweight as a child, or having a role model/close friend who was overweight would therefore logically reinforce the developement of feederism. Going by this logic almost everyone in the Western world should have a fat fetish, however you have to realize that early life experiences can be viewed as a series of checks and balances. If you are frequently being shown that fat is a negative you're more likely to believe it. If you're more often shown that it's a neutral topic or slightly beneficial then I suppose your chances for developing a fat fetish go up.

As to women...girls are much less likely to be comfortable with being seen as "strange" and therefore are more likely to keep any "kinks" to themselves than boys.

Exactly.

For some people this doesn't even develop, I know I was born like this, I never remember not being into this stuff.

I dont think anything that happens in your life causes it, I think its just like being gay or having another type of fetish
you're just born with it

Not sure if you meant to say what you said, but I disagree:
Being gay isn't a fetish, it's a sexual orientation. Being more attracted to brunettes is a preference, so is being attracted to big girls or guys. Feederism is a fetish, just like getting turned on by shoes or something. I'm making this sound more black&white then it actually is because some things are obviously (or far less obviously) related, but that's my perspective.

We're humans, the world consists of shades of gray, everybody just gets a different set of pencils to add some color to it .

I can always remember being very young and stuffing my clothes with pillows to look fat. There was a store in my town that sold very large clothing... and remember seeing the really large clothes and often wondered what it would be like to fit in them.
Then I also remember one summer when I was under about ten I used to make fried egg sandwiches...and I would eat maybe three or four a day loaded with mayo...my grandmother grabbed my belly once when visiting after that summer and said "whats all this?"which made me very embarrassed.
Then as I entered high school... I only had the eye for the girls that had hips and big "booties"...I never dated the larger girl in school but I did however add a few pounds to my high school gf because the only time her parents would let her leave with me was to get ice cream or a sandwich...she never got plump but did get awfully plump around the middle.
Then in college 1998-03...the internet arrived and at first I thought I had a pregnancy fetish but it turns out that I just like girls that have a little bit (or a lot) of belly!
I really don't know what may cause a person to become an FA, I do however feel isolated in such a way that I don't talk about it. I keep it to my self and only find women with a little to a lot extra sexy...

Yeah I didn't think she meant that, but the way it was written seemed 'out of place' for some reason. No hard feelings here.

That is exactly what I meant Kid A !! Thankyou lol
I am totally aware that being gay isnt a fetish

Except not. There's a pretty distinct difference between someone who prefers to have a fat partner and someone who requires a fat partner to be sexually satisfied.

In my opinion, FA can mean both, since FA is a term that shouldn't have the baggage and bullshit that's so often attached to it. An FA is someone who is interested in a fat partner. This covers the broad spectrum, I think, of interest, from preference (I just like it better) to what could be considered a sexuality (I just don't get aroused by thin partners) to fetish (fat partners get me SO HOT) to fixation (I'm sorry, I totally ignored everything going on just then because oh god fat).

I know the one you mean, made a huge impression on me too that cartoon did.

The best part is that they both found it so hilarious, rather than freaking out about suddenly gaining hundreds of pounds. LOL
