Really small annoying compulsions

So I’ve had small compulsions for ages now, and I’m not sure whether they’re anything I should worried about. Just choose whether they’re normal overall, they feel similar enough to me.There are two examples I have of different ones. Basically, if I’m offered two options, one for me and one for someone else, I have pre-chosen which one I want, and If I don’t get it, I’m super uncomfortable. For example, a teacher put a pile of two identical test sheets in the centre of a table with a friend and I and either end. He ended up choosing the one that I “pre-chose” and I had to switch with him otherwise I wouldn’t be able to do the test (I was very stressed about it). This happens with little things like glasses of water I’m handed, food I’ve prepared etc. It doesn’t matter whether I get more or less out of it, just that I get the one I choose.
The second one is that I choose a particular finger subconsciously and I have to constantly tap it to satisfy something idk. I’d be playing a game and I’d have to tap a particular button on my keyboard a bunch of times, or drawing, and if just have to scribble in the same spot for a while.
To provide a bit of a extra context, I do have a habit of shaking my limbs when I’m concentrating or feeling intense excitement, family went to the doctor a bunch of times as a kid (early 2000s) and nothing came of it. May also be a part of all this.
Is this anything I need to worry about at all? I’d really like to know if this is just a way my brain works or whether I have to get it checked out or something.
