So based on my experiences with friends and family, I do experience less pain and am less sensitive to spice than them. There will be things that I am genuinely unaware are spicy but friends and family are telling me it's hot, but I think there's also the aspect that when it starts to get really hot I just enjoy the intensity of the sensation and pain.
The super mild stuff, like tabasco, tapatio, sriracha, cholula etc, I can sense the spice but it's mostly just about the flavor. Like I can literally drink the stuff straight out of a glass and it's like chili flavored vinegar, with only a bit of heat as it hits my throat.
Straight jalapenos just taste kind of sweet and fruity to me, with just a hint of spice, but these are some of my favorite just on flavor alone.
Bird's eye chili, thai chilis be they fresh or dried or in vinegar, feel only a bit hotter than tabasco/jalapenos to me.
On my recent trip to Thailand I really wanted to find a place that would blow me away with heat. I would always ask for everything 10/10 thai spicy, and I got to the point where I was additionally just covering my noodles/curries with a 0.5 cm thick layer of whatever fresh/dried chili they'd have on hand, and then adding more throughout the meal, to the horror of the poor vendors/chefs. It just tastes great, really love the flavors of the chilis but it doesn't honestly taste that much spicier to me than tabasco or jalapenos (which is why I kept adding more to try to get it spicier).
Every time I eat at a restaurant that has a spice scale I always go for 5/5, 10/10, nuclear/danger/whatever, and 9.5/10 times I will be disappointed. I get the feeling that most restaurants just err on the safe side so that people don't return the food for being too spicy.
For some reason habaneros to me are a real jump up. Some really pure habanero purees can get pretty damn spicy. I still douse my food in it, but this is where I can really start sweating and breathing through my mouth. For whatever weird reason I still find it super enjoyable but definitely straddling the border of pain/pleasure.
I got a Hot Ones variety box including the Last Dab, and I was just using that as regular hot sauce for my pizza and burritos. Like a good 1-2 teaspoons per bite? Honestly for whatever reason less spicy than some of the habanero sauces I've had.
Have not tried straight ghost peppers/carolina reapers yet. For some reason they scare me, but I'd love to if I came across them.
