I think it’s incredible how the internet can connect people who come from different planets like this.
I mean yeah, if food is more bitter than it is sweet then it’s unpleasant to me (even the darkest chocolate has a lot of sugar) but that still doesn’t directly stimulate pain receptors like capsaicin does at any level. Very low levels of “heat” (pain) are indeed tolerable to me, but No level above zero is more enjoyable than zero, for any type of food.
I also don’t understand that concept of “too sweet” (for things that should be sweet, I am not talking about pizza for example). The only thing that stops me from just buying sugar in bulk and eating bowls of it at a time is concern for my health/teeth. (Which of course is a strong concern, and so far has managed to keep me from being diabetic)
I seriously can’t imagine a flavor so good that I would be willing to experience significant (let alone severe) pain in order to taste it. (Nor Have I been able to taste any extra flavors in even mildly spicy food.)
I don’t doubt your experience, but I absolutely can’t relate to it, or for that matter comprehend it.
