That's an amazing article.
I read recently that "wanting" and "liking" were neurologically different; dopamine makes you want, and opiods make you like.
Does this mean that BDSM suffering is experienced as real?
For example, you wrote that a submissive gets an endorphin rush being around a dominant. That seems to explain why people like me enjoy playing at being a slave; we're hacking the ancestoral pecking order in order to get high.
Presumably, you can like being a slave, while not wanting to be one.
So, a submissive should be awash with opiods, dopamine (because that's produced by things you have a strong reaction to) and endorphins.
If so, how would they interact?
