I hope you can let this go. It was not your intent to do something illegal and you almost certainly didn't accidentally do anything illegal either.
It is ok to like even gross things, lol. Women make money on onlyfans doing things I find gross but they have a paying audience. You are obviously not alone if you found others who were into the same stuff. It's going to be ok.
Don't overreact. Breathe, give yourself grace, you are a person like all of us.
And again I hope you can relax soon.
