Wow, I’m surprised the OP didn't delete their account after all that lol.
Answering your question mate, yes I was definitely conflicted, and I shared the same feelings, guilt, shame, self-hatred, it basically consumed and made me fear my own sexuality from before I even started school up until I found this site and realised I wasn't the only one.
Now before anyone jumps on my back about degrading women by not embracing my fetish, let me clarify, my fetish has always been one of feederism and weight gain, I’ve never had just a preference for fat women, I find women of all sizes attractive, yet I can only get turned on by the idea of feeding and fattening and weight gain.
As such, the thoughts which caused me so much pain were those I’d have of my fellow female classmates being force-fed into extreme obesity, inflated like balloons, magically waking up double their original size, etc.
I couldn't help these thoughts, they made me feel good, yet I spent my childhood and puberty trying to escape from and deny them, because I could think of nothing worse than actually doing that to these poor girls, or heaven forbid, tell them this is what I think about them. I was a shy, quiet guy, I was terrified of how demonised I would be by everyone if they ever found out what I secretly thought about at night.
Fortunately now I know better and am a lot more comfortable with my sexuality. I'm aware that there are others, both men and women who share the way I think and feel. I know it is possible to share this fetish with someone else, be it just the fantasy or some degree of reality.
So take it easy my friend, maybe get more involved in the wonderful community here or on other related sites, and allow yourself to become comfortable with who you are, because there is nothing wrong with it.
