FAscination:
I am sure that there must have been tons of research looking into why people have certain sexual preferences. I don't think we will ever understand this or know why. I have had this fascination for fat for as long as I can remember, so I am sure it must be something unconscious from very early childhood or something I was born with.
For me, it is mostly about the �softness�. Someone could have the biggest belly on earth, but if it would be hard to touch, it would not do much for me. Touching, feeling and cuddling a soft body, or the anticipation of how soft someone must be when I see soft curves, is what gets me going. Is this because it reminds me of soft cuddles as a baby, or the contrary, a lack of them? I don�t know. Is it something genetic? Possible, but then it must be random genetic variations, because fatsexuality doesn't usually seem to run in families.
I have thought about this a lot, seeking answers for my preference because I was struggling with it when I was younger. But you just have to accept it as it is without asking why because it will not go away. It is like if we were on a train that never stops. You are on it and you can't get off. You can see the outside world through your window, but you are not part of it. You may dream about it, pretend to be part of it, but you're not. You're fatsexual and you have no idea at all what other people find so attractive about skinny people. You can be sad about being on this train and constantly be staring out of the window, or you can sit back, get to know the other passengers on the train and enjoy the ride wherever it takes you.
Of course, this is just a metaphor, don't take it literally. I don't mean we are people in a different universe, of course we interact with "normal" people as well. But sexually, I feel on a different planet. I have no idea what drives other men so crazy about skinny or normal sized women. I have fallen in love with skinny women, but it was purely platonic, no sexual feelings involved at all. Sexually, I will never feel complete unless I am with a big woman, and I have learnt to accept that as it is without continuing to wonder why.
Part of the reason we have this conversation is the perceived societal "norms" which tell us this is something abnormal and perhaps deviant or perverted.
However, it doesn't work that way at all. We wouldn't have a conversation on these preferences if they had to do with liking men with muscular chests (rather than flabby ones) or women with narrow waistline (rather than roly-poly wide ones).
But throughout history, what passes for desirable (sexual or not) has changed, and different cultures treasure different features and appearances.
