As for spicy foods? I LOVE eating them!
The thing is, there are different kinds of spice for each cuisine. Indian curry will have a different kick to it than Mexican food or Thai food. I enjoy a little spice (red pepper flakes or hot sauce) on things like Chinese takeout, pizza, wings, burritos, and cheeseburgers. I think I can handle a medium level of spice, perhaps just on the very edge of hot. If there was something on the menu called "The Insanely HOT, Heart-Stopping, Face-Melting Volcano Wings of Death," I'd pass.
And then there are those freakish ghost chilis and Carolina reapers that few people can handle....except for Sean Evans, the host of Hot Ones. He's built up immunity to the Scovilles and barely breaks a sweat during his celebrity interviews. Meanwhile, the celebrity interviewees like Neil Degrasse Tyson, Shaquille O'Neal, Scarlett Johansson, and Gordon Ramsey are drenched in sweat, downing glasses of milk, and cursing him out.
