I've lied to my more closely valued friends and have decided to take it to the grave, is that ok?

I can't bring myself to telling them about the truth about my past. We've been friends for at least 5yrs. now. I lied about taking someone's virginity back in highschool during prom night. That was the idea at least, we just didn't do it. Everyone else just assumed because the situation implied that it happened. I've never taken a virginity. I've only ever had mine taken. My friends and I are still pretty close I think I'm just beating myself up about the fact of lying and then taking it to the grave completely before having them ever find out.
