I'm 15 and have never dated anyone
Have you ever wanted to date anyone?
No, I never wanted to date someone at this age.
You're still 15 so you have plenty of time to ahead to date people. It's good you're not focused on it at this time of your life.
I feel like my time might be running out though.
It is perfectly normal to not have dated anyone at any age. Not all people are the same. You should just wait until you are ready and not be pressured.
