I have gotten it at least twice, both really mild. Probably gotten it more times, but haven't bothered testing after the results didn't matter for anything. Anyways, my wife and my son (1 and a half years at that time) had it and I didn't get it that time. It was pretty much unavoidable to come into contact with the virus given the age of my son, snot and saliva pretty much everywhere. I was quarantined for 11 days, feeling perfectly fine and healthy. A little bit inconvenient, but pretty nice home vacation. Did get it some months later though, but milder than some flus I've had. Got quarantined for that too, but 7 days because rules changed in my country. Again, nice home vacation because I was really only feeling a bit sick for 2 of those days.
You could just be asymptomatic. You probably wouldn't test yourself for fun if you didn't have any symptoms to even slightly suspect it's covid-19. If you ever did test yourself it might just have been another very common virus going around.
