No, I see what you mean. When I posted what I did, I reread it and thought it really wasn't saying what I meant, but I didn't know how to put it and, frankly, was also kind of too lazy to revise it. Yes, it's possible to overcome the sensitivity to texture, just as it's possible to try and overcome difficulty with social situations. But because the ASD is typically (at least according to studies) behind the problem, I feel it is okay to say that I do have a pickiness to texture due to my Asperger's. I didn't mean to imply that it's impossible to get past it, however.
For me, if I encounter a texture I can't stand, my throat literally closes up and I can't swallow. I'll start gagging. If I, by some miracle, manage to get it down, the lingering feeling in my throat will make me continue to gag and eventually vomit. It's really strange, especially if this happens with something I find tastes really good. I wonder if that's how people who are allergic to something that they still enjoy the taste of feel. I used to love the taste of grape-flavored anything, but had a liquid grape medicine with a terrible texture. I would vomit every time I took it even though I loved the taste. Of course, that eventually turned into me feeling sick every time I tasted grape, and I also can't stand the shade of purple of that medicine (seeing that color will actually make me nauseated!). All because of a texture...
