Should I get tested again?

I've had sex with one person. I got tested after the first time we had sex because it was unprotected. He was meant to get tested before we had sex and it didn't happen.

Anyway its been some years. I never thought he was unfaithful or anything, but I just thought maybe I should get it done now. Like I'm going to ask the guy I'm dating if he's been tested lately and think it would just make sense if I did the same.
