The more I think about it, my taste sensitivity since I was young is perhaps the most obvious symptom that I may be autistic, so I have to go with that. Although it's not that simple, because it's combined with mainly smell and sometimes sight. It's mainly the combination of smell and taste. Smell by itself can be bad, but it's far worse when combined with food.
I have an extremely sensitive gag reflex. If the texture is slightly off from how something is normally prepared, it will not stay in my mouth, to put it vaguely. This is very bad, because this means that sometimes when I order food from a fast food place or such, I will find out that I'm not able to eat it. Like when it comes to Arby's, there is one and only one way that they prepare the meat that I can eat (very thin). And I love it when they do that, but I can not eat it otherwise. Very frustrating.
I cannot eat the vast majority of what other people can eat to begin with. I don't know how to maintain a balanced diet, I do not know how to diet because there are so few things I can eat that if I cut things out then I have very little left. I have had to take pills to keep my weight down.
It's so embarrassing socially, too. There are so few places that I can go out with friends and family to eat. I can not try new things, because the chance of me then gagging in public is insanely high. It happened at a supper with my ex (back when we were dating) and her family (it was a restaurant, not prepared by themselves thankfully), and it has happened when other people buy me food and then I can't eat it, causing them to waste their money and I hate it so much, even beyond the embarrassing factor. I'm just straight-up complicated when it comes to food, it's too much drama for most people, I bet.
As I said above, I have issues with smells. I do not eat in the breakroom at work because the smells in the breakroom are just overwhelming for me. We're not technically supposed to eat at our desks, but I don't know what else to do.
Go eat outside? Well, no... because you see... I'm also extremely sensitive to sunlight. The sun is so bright to me that I can not do anything out in it and I get super irritable. I also hate the way that the heat of the sun (unless it's cold enough) feels on my skin.
I didn't put sensitivity to light at the top because I have little to no problem with indoor lighting ,which I see so many autistic people do. For me it is outdoors sunlight. It's also headlights from cars at night.
When I was young, I did tend to prefer sitting in my room in the dark. I do not think that was a sensory thing, but it is something for me to think about. The only reason I stopped doing it was because I got eye strain was concerned that sitting in my room in the dark on my computer for hours at end wasn't a good thing for my eyes...
I am sensitive to sound, but I feel like probably less than everything else. I do get super irritated with people playing music outloud on their tinny cell phone speakers in public. Not only because I think that is downright inconsiderate (why would anyone do that?!) but also because the sound is grating to my ears. I also have a lady at work who deals with some kind of issues where she coughs, hacks, and sniffs/blows her nose a lot and that is grating to me as well. I feel bad about that one, because it's probably just health issues and not her being inconsider. But it is an every day thing and I cannot handle it, at all.
After high school my ears started getting more and more sensitive to the point where I got discouraged from performing music. I don't know what the reason for this is. I will only play music now with earplugs. It is not optimal for music performance with others because you block a lot of necessary things for good performance.
Overall, it is taste and smell that I experience the most sensory issues with.
