why tickling causes discomfort

since endorphins are produced during tickling

Probably because we are conditioned to sense fear, and take action if something is crawling, or slithering, or unnecessarily touching us. I try to train my brain to enjoy the sensations when they are clearly playful games, and intimacy but it isn't always easy.

No matter how well you train your muscular-nervous system; ticklish always seems to win.

since endorphins are produced during tickling

The human body is a complex system and most of it's functions and reflexes are not one-dimensional. The body also releases endorphins during painful stimuli. However, pain and discomfort often persist. The endorphins are there, in part, to reduce the pain, but don't often regulate it to the degree you'd expect from certain pharmaceutical drugs. When someone is tickled, the nervous system and brain are jolted with the sensation and all sorts of biomechanical and biochemical responses occur. One can have a multi-dimensional cocktail of discomfort and pleasure in experiencing a single stimuli. It's even more fuzzy than that when you factor in psychodynamics and individual variation–the "lenses" through which the individual perceives the experience. So, some people release less endorphins, and others more; some people don't experience tickling as any kind of discomfort, while others experience it as unbearable torture; and some people just aren't even ticklish at all (despite my wife insisting that those people are actually aliens 😂).
