I'm not sure how long I've been like this but at one point I noticed that I seem to have sensitivity to A LOT of textures, most of which I loathe to touch, and actually causes some discomfort and anxiety if I touch these certain textures. I could make a list but I doubt it would be helpful since there doesn't seem to be a pattern but for the most part I prefer to touch smooth textures and loathe touching rough textures, but if I did make a list it would be pretty long, which doesn't seem normal to me.
I'm sure that everyone has a certain texture that they dislike, for example my grandmother hated touching cotton balls and cotton swabs, and my father hates touching styrofoam, but these are just one thing, and not many like myself.
I think I read somewhere that this sort of sensitivity was part of something bigger, but I can't remember. I always just considered it a quirk that I had, but I'm curious to know if anyone else has the same thing or might know if it's connected to something else.
