If answering yes, please write some detail as to what happened, where you were, conditions, etc. Let's go with the last 5 years because memories and details get pretty fuzzy and conflated after a few years.

I'll define "sunburn" as enough of a burn to be painful to the touch, persist for days, or worse. Getting slightly flush for a day or so I would define as "getting some color" but not "sun burned".

And yes, I know that even if you don't get "burned" per se, cumulative exposure could eventually be harmful.
