I find this kind of hot to just be a little too masochistic for my taste. I want to taste what I'm eating and not have my mouth burning from the inside out. I already sweat enough without super ass hot food helping lol. I do like a very good medium heat though where I can still enjoy the food but still get a little burn going on. I'm a light whipping/spanking and not a bleeding/genital clamp kind of masochist
It doesn't burn the insides of my mouth for some reason... just the lips.
I think that years of loving extremely hot spicy sauces/food has conditioned the insides of myself to be somewhat immune from the hotness/burn. It doesn't stop me from tasting either. I really enjoy the taste of some of the much hotter peppers/sauces. However, that isn't true for the taste of all of them.
The outsides of my body did not develop this same immunity. My lips can't always take it. Another problem that happens for me comes from me physically slicing very hot peppers up when I'm making sauces/food. You really pay if you rub your eyes after doing that. You will also pay if you go take a leak soon after as well. LOL
