Hot spicy shit is bad times. Spicy is good when it gives some sort of flavor. If something is so spiced up all you taste is burning, and no other flavors, just burning, something is not right. Maybe I am missing something, but if I wanted that effect why not just eat fire? That's what extremely hot crap tastes like, textured burning. It's almost like some sort of pissing contest to show off your manliness, and nothing more. I can eat it just fine, but what's the point? There are far better ways to show how "manly" you are, and speak volumes louder than having your mouth on fire for a few minutes. Stuff like punching through brick walls, or being Segata Sanshiro. 
Sometimes it gets so hot that it tastes bitter.
A quick word on hot sauces. There are a TON of different ones. And hotter doesn't necessarily mean bitter or sour. That's just a style of hot sauce. I prefer tobasco on once-over-lite fried eggs. That hot sauce mixed with the runny yoke is nom-nom-nom delicious. But I don't really use tobasco for much else. I have a whole array of different kind of hot sauces. Some for making soup, some for tacos, some for burritos, etc. Some have a lot of spice and hotness, some have little taste and a lot of hotness. It depends on what I want it on. I don't want that spice taste on some foods and other foods I do. I do like to mix in spicy/hot sauce with new bottles of spicy v8 - cause they aren't spicy enough or hot enough. And peppers too. Love fresh pickled jalapeños that still have a crunch and plenty of seeds. Habanero, serrano, roasted chiles. Hmmmm.
I can pretty much eat any type of food, but that doesn't mean I don't like quality/good food. The few things I don't like are; bell peppers (don't like the taste), cream of spinach, and too much yogurt. I like yogurt, but eating too much makes me gag for some reason. So I only eat small amounts of it at a time. Also not a big fan of BBQ sauce. It's ok, but usually cook my pork ribs with just onion/garlic-salt seasoning.
I never had a problem with seafood. I don't care too much for fish, unless it's prepared certain ways. Sushi being one of them. I love sushi (raw fish). And I love any type of shell fish (clams and red sauce spaghetti, shrimp and alfredo, butter and garlic scallops, deep fried mini octopus, etc).
I'm not afraid to try new food either. I like eating chicken/turkey hearts/gizzards and similar (I usually save the liver for making gravy - cause it's a bit to dry to eat).
