I was unbothered by it as well, at least intestinally, the physical pain of something hot enough was certainly something I could experience and dislike at the extreme end but my stomach and bowels would have been fine. That it until about the past 5 years or so when my stomach suddenly decided it couldn’t handle all kind of things that were never a problem before and now I totally get what people were talking about. It’s pretty sad, I miss being able to reliably tolerate highly spicy food.
