Do any other binary trans folk "They/Them" themselves even when they're not?

I'm registering For college classes right now and on the profile section, you can put your personal identifiers, and it just shows app on the tip of your profile for professors, and like if you have a preferred name or pronouns or something like that. I keep hovering between finalizing with "he/him" , or "they/them" not Because I have any questions with my own self identity, Like, I am a trans guy.I have known this inside of my own head for most of my life , but like I don't know , putting it down on paper , makes it feel more real. And I know that it's literally not a big deal.And the professor is gonna look at it and probably not care at all and just call me whatever they think I should be called, but like I don't know I feel like i'm hyping it up in my head too much. On one hand.I feel like if I put them they/them there's a better chance that I might at least not get called she, but on the other hand I don't really want to be called that either. And if I put he/him I know there's no hope the teacher's gonna take one look at that sheet.One look up at me and think that there was an error. So I guess my question is , do any other people have this sort of like dilemma , not with knowing what they are , but with what and how to tell people?
