Help!!

So I hooked up with a friend the other day after a part (we’re in college) we talked about it 3 days after it happened and decided to forget about it because he’s on the men’s basketball team and I’m on the women’s basketball team so we see each other all the time. So we agreed to forget it happened so it’s not weird but it still seems weird! Any advice on how to move past this because we still have 4 more years of college together plus we go to the same parties EVERY WEEKEND! help!
