ELI5: Why humans enjoy spicy food?

I love spicy food even though it can be a bit painful to eat things as spicy as I enjoy. The aftermath of spicy food can be pretty awful as well, so why do people enjoy the mouth burning sensations of spicy food?

Because eating spicy food causes your body (pituitary gland and hypothalamus, specifically) to release endorphins.

Endorphins are the same chemicals your body produces when you experience pain, orgasm, etc.  They have an effect similar to opiates, causing pleasurable feelings and numbing the sensation of pain.

That, and there is the social "my balls are bigger than yours, watch this" aspect.
