This always confused me. I mean, I don't care that I'm into body inflation, I'm just confused why.
When I was 10, Charlie and the Chocolate Factory (2005) came out. I always loved the blueberry scene more than any other scene. There's something about seeing a girl turn into a spherical, 10 foot tall, 1 ton blueberry without her knowing it would happen and being rolled around by workers against her will was so damn cool in my mind. Then, a few years later, I looked at it a little differently, seeing inflation art on the internet. I thought it was...
sexy.
I was like, "Why the hell do I have a boner watching something that was originally supposed to be innocent but turned out to be incredibly sexy?!" I said that internally of course, or otherwise I'd have to explain what I was saying to my parents, which would have resulted in something awful.
Is there any explanation for this? I really don't know why I find inflation art so damn appealing. I'm not angry at myself, I'm just confused.
While I can't give a defenite answer, I can give a couple of suggestions:
It does vary from person to person, and there isn't always a clear answer, even an answer at all than your brain just hardwiring that, but I can say that you are not alone, and there are literally thousands, if not hundreds of thousands that share your similar fetish. Mine is more specific towards belly inflation/distention myself, but that's just part of my kinks, and like all of us here, inflation is just appealing to us.
Also, I had a somewhat similar reaction as well. You might not know this, but one of the members on this site runs an inflatable latex garnment site, and one of the articles he sells is in fact a latex blueberry suit that you can purchase. (Link: http://squeaklatex.com/ballberry.php)
One more thing, don't feel like it's odd. Fetishes generally aren't chosen; they're a sexual adaptation hardwired by the brain for survival.
