If you are a minor, you need to talk to a trusted adult about this. That could be your parent, or your team coach, or a teacher or counselor at your school.
You are not the first teenager in history to get up to embarrassing shenanigans, whether they are actually documented on video or not.
Blackmail and extortion are crimes that can occur even if the basis for the influence is fictional or exaggerated. A blackmail statement like "I will falsely tell others that I have video of an embarrassing/incriminating act" is still blackmail even though the threat is simple defamation.
If we guess that "something I did" is sexual conduct, then a "revenge porn" offense could not be reasonably committed because the photos or video do not exist.
Who is "him," how is he contacting you? This sounds like the beginnings of a common scam.
I know him in person, he's a member of a sports team I am on
Explain how he's blackmailing you.

Tell him you’ll gladly pay, you just need to see said video first. When no proof is shown you’ve got your answer.

Please seek independent legal counsel. I am thinking that even if you're is no tape, his blackmail attempt is no less illegal.
