I love sweet food, and spicy food (though not like the Mad Dr. and associates). I prefer a nice mild spice to much (though certainly not all - keep the peppers out of French dishes with cheese or cream!) of my cooking and eating. By "mild spice" I mean several jalapeños or serranos (depending on the dish and size, etc). I tend to put a few good dashes of tabasco in otherwise "normal" soups, and I splash it on over Mexican food.
However, I have made dishes that were outrageously spicy, even by the standards of those who like spicy food; We once made a single Thai dish with 10 serrano chilis which were blended (seeds and all) into the dish (along with the other flavorings). That one'd bring tears to your eyes, for sure.
I would just like to also make the comment that Thai curries are VERY different from Indian curries, and it's particularly important to differentiate the two; Thai curries do not actually contain curry (but rather contain curry paste). I haven't particularly liked the Indian curries I've had, at least not when compared to the bliss that is Thai curry (if you couldn't tell, Thai is my favorite kind of food).
