Bedtime for 16 years old boy

I am 16 years old. My bedtime has gotten a little later since I turned 16. On weekdays, it's 9:30 p.m., whereas before it was 9 p.m. And on weekends, it's 10 p.m., whereas before it was 9:30 p.m.

Is that normal for my age? I don't talk to my friends about it because I'm embarrassed. But as far as I know, they don't have a bedtime at all, or they go to bed later. Oh, and my parents are also very old-fashioned.
