More of a wibbles material i think
Sometimes pain is quite fun to test own limits like how much i can take as example heating up coin so its hot like fuck and press it on my chest and see how long i can last that pain.
Sometimes its just the shit.
Pain is a necessary part of life.
There have been children born without pain and they end up horribly hurting themselves by laying hands on stoves, etc.
Pain is a necessity because it lets us learn what is dangerous and what actions to avoid.
Nobody "enjoys" pain. It is meant to be an unpleasant sensation to tell the brain that tissue is getting damaged somewhere. Some people live such dull lives that they hurt themselves simply to feel alive. That is an entirely different topic.
