I wrote a homoerotic fanfiction about my high school teachers and I can never get rid of it

To preface, I would like to say I really care about my teachers (not in that way, ew) and really respect them. I've never had and never will have sexual feeling towards them.

Though I hate it, the only reason a lot of people like me is because of my out of pocket (and unfortunately sexual) humor. A few months back, I was on a school trip with some friends that I never talked to much. At the time I was extremely awkward around them and felt like I needed to break the tension somehow. I don't remember the details but I think some of them were talking about fanfictions or something? So I had the genius fucking idea of writing smut about my male chemistry and history teachers because apparently that was so fucking funny. They absolutely loved it, but I had made the crucial error of airdropping the whole story to them. I know some of them shared it with other people, and I have no idea how many people know about this thing, and know that I was the one who wrote it. I'm especially scared that a teacher or someone higher up will find out about it, and the impact that it could have on my life. I wrote it like 10 months ago and so far nothing bad has happened, yet I'm still scared that one day it will come back up with my name on it. I realize now how stupid writing it was, and I never wrote it with any sort of sexual intentions. Just something stupid to get people to notice that I exist. Should I laugh this off as a stupid thing I did, or should I be more worried?
